From his early appearances as a nameless monster in the first season to his emergence as a lovable, furry old pal, Grover has been an active and eager assistant in lectures and performances, notably those by Kermit the Frog, Herbert Birdsfoot, and The Amazing Mumford. As Children's Television Workshop researcher Gerald S. Lesser put it in Children and Television: Lessons from Sesame Street, Grover "seeks opportunities to be helpful even when this places great physical and mental burdens upon him; often ends up in total exhaustion as he amiably extends himself to the utmost to co-operate."
|Picture||Theme / EKA||Description|
| Soft and Loud|
|Kermit uses a radio to demonstrate "soft". Grover shows up and wants to talk about loud, turning the radio up. After the two demonstrate soft and loud a few times, Big V appears and eats the radio.|
| Kermit talks about the word "in," and the monster wants to help him teach. Kermit has a big box that he wants the monster to get inside, but he can't seem to grasp the concept of IN ... he gets beside the box, on the box, and under the box. Finally, he reveals why he can't get in the box: because "Fred" is already inside it.
| Nine Blocks|
| Grover helps Kermit count nine blocks, bringing back one block at a time from the block pile.|
This sketch was reworked a few years later, with nine blocks being condensed to five.
| The OP Family|
|Herbert Birdsfoot displays the letters O and P, mentioning that they're the OP family. When he adds an M for "mop", he has Grover fetch a mop. When he adds a DR for "drop", he has Grover drop a heavy rock. When he adds an H for "hop", he has Grover hop repeatedly until he faints. Herbert then adds a FL for "flop" and a ST for "stop".|
| Hopping Poem |
|Herbert Birdsfoot recites a poem with OP words, counting on Grover to hop whenever he says "hop" — repeatedly until Grover faints.|
| The AN Family|
| Grover and Herbert Birdsfoot discuss the AN family. Herbert demonstrates the words themselves, while Grover provides visual aids.
Part 1: The first word they talk about is RAN. While Herbert talks about how to make the word, Grover keeps running around the scene until he tires himself out.
Part 2: The next word they demonstrate is CAN. Grover brings out an armful of soup cans and stacks them all up. Then he clumsily knocks the tower over.
Part 3: The final word for today is FAN, which Grover says is one of his favorite words. He brings in an electric fan and turns it on full blast. Everything is blown away, including Herbert and Grover.
|Grover assists Herbert Birdsfoot in a demonstration of the word "THE", by holding a sign with the word as Herbert tells a story and rings a bell whenever the sign is needed. As usual, Grover wears himself out.|
| Counting blocks|
|Herbert Birdsfoot arranges three blocks for Grover to count. No matter how the blocks are arranged, they still add up to three. Herbert asks Grover to count some oranges as well. Grover confesses that he's good at counting blocks -- but he doesn't know how to count oranges!|
| Over and Under|
|Herbert Birdsfoot demonstrates "over" and "under" by having Grover lie on a mattress. Then Grover lies under the mattress, and Herbert drives the point home by adding more objects over Grover.|

| The Letter M|
| Herbert Birdsfoot wants to demonstrate the letter M. Grover enters, making "Mmmmm" noises, so Herbert recites a poem full of M words, having Grover make the "Mmmmm" sound at intervals. When the poem is over, Herbert discovers that Grover's mouth is stuck together after eating peanut butter.
| Long and Short Ladders|
| Kermit has Grover show the difference between short and long with ladders. He's amazed that Grover can carry the long ladder by himself, but then sees that Grover is on both ends.
| Mumford's Pineapple Subtraction Trick|

| The Amazing Mumford's Suspension act|
|Grover volunteers to be the Amazing Mumford's assistant when he performs a magic trick. The trick involves Grover sitting on top of a platform held up by a pillar, which Mumford will yank from underneath the platform, and the platform will not fall. The trick works for Mumford ... but not for Grover when he tries the trick on Herry.|
|Kermit teaches Grover to read his sign with "NO" written on it.|
| Raising and Lowering Trick|
|The Amazing Mumford performs his "Up and Down Trick" by raising and lowering Grover.|
|Kermit teaches Grover the word YES.|
| 5 Blocks|
|Grover helps Kermit show the number 5 using blocks, but Grover doesn't know how many to get (he can't count to 5). Kermit has him go back and forth bringing one until there is five.|
| Short and Long|
|Grover does things for a long time while Kermit does things for a short time. Grover gets worn out and asks to switch places, and then they demonstrate by tickling each other.|
| Grover assists Big Bird in demonstrating the number 2, by doing 2 chin-ups. Big Bird asks him to repeat the exercise twice to make sure that the audience really gets 2. Then Big Bird announces that Grover will now demonstrate the number 18; an exhausted Grover falls off the bar and lands in a heap.
| Horse and cart|
| Kermit, Farmer Grover and Fred the Wonder Horse show how a horse-and-cart works.
| Up and Down|
|Kermit has Grover help him demonstrate up and down by having Grover climb UP a sky-high flight of stairs -- while Kermit takes the elevator to the top. Exhausted, Grover faints and rolls DOWN the staircase.|
| Grover turns into a rabbit|
| Grover watches The Amazing Mumford as he practices a magic trick, to make a rabbit magically appear out of his hat. Though he fails to get a rabbit to come out of his hat, both are oblivious to the fact that Grover has turned into a rabbit. (|
| Rhyming Trick|
|Grover volunteers to assist Mumford in his rhyming magic trick, making three things come out of his hat that rhyme with knee. Grover guesses the first one, but doesn't get the last two right.|
| Heavy and Light|
|Kermit and Grover demonstrate the difference between heavy and light. Grover carries heavy objects, and Kermit carries light objects. Grover gets tired, and asks Kermit if he can carry something light for a change. Kermit obliges. He carries a giant sandwich... while Grover picks up a helium balloon, which carries him away!|
| Near and Far on Ice Skates|
|A full-body walk-around version of Grover demonstrates near and far by ice skating, with Kermit the Frog giving commands in voice-over.|
| Light and Dark|
| Kermit (Steve Whitmire) intends to talk about light and dark, so he turns his living room lamp off. Grover enters, leaving the door open so that the room doesn't stay dark. He tries to help by eliminating all light in the room so neither of them can see.
|Short and Long|| Grover assists Zoe in demonstrating the difference between short and long, first by hopping and then hugging.
