Picture	Theme	Earliest Known Appearance	Description
	Front and Back	Episode 0330	Grover demonstrates front and back by telling the passengers on his elevator where to stand. (Guy Smiley appears in this sketch - he doesn't have any dialogue, but Grover addresses him as "Mr. Smiley".)
	Only Five	Episode 0689	Only five people are allowed on the elevator at one time, so Grover counts out five passengers. But then he's not allowed on the elevator himself; he would make six.
	In and Out	Episode 0711	Demonstration of in and out by Grover. People prepare to ride the elevator, but Grover annoys them by the "in" and "out" lessons. Soon Grover lets them into the elevator without him, but they can't go up or down without an operator, so they break out and take the stairs instead. (features Farley, Roosevelt Franklin, and a Fat Blue AM, played by Jim Henson.)
