Garfield is a famed comic strip cat created by Jim Davis in 1978. The selfish, gluttonous feline has also starred in numerous television animated specials, the Saturday morning series Garfield and Friends, two live-action/CG feature films, and has appeared on countless pieces of merchandise, such as coffee mugs and suction cup dolls.
In "The Real World Muppets" segment of Muppets Tonight episode 205, Bobo interrupts Clifford reading the comics in the tub, and expresses his fondness for Garfield, and the way he continually tricks Odie.
The animated series Garfield and Friends occasionally made references to the Muppets.
- "Attack of the Mutant Guppies"- A group of giant radioactive mutant guppies disappear at the end of this episode, and show up in the subsequent "US Acres" quickie, scaring away Orson and Wade. One of the guppies says, "Come on, guys, let's go see if we can get a guest shot on the Muppet Babies." (Both series were airing Saturday mornings on CBS at the time.) In the Spanish version, this was changed to Sabado Gigante, a variety show popular among the Hispanic people.
- "Flat Tired"- Garfield is too tired, so the director needs someone to fill in for him. Odie tries to meet the director's requirements, but the director says jokingly, "I know who we can get! Get me Kermit the Frog on the phone!"
- "Mistakes Will Happen"- As one of several deliberately-made mistakes in the episode, Jon addresses Garfield as "Kermit" at the end.
- "Binky Gets Cancelled Again!" - Garfield (who says something different at the start of each show) says "Today's show is brought to you by the letter K and the number 9," referencing the Sesame Street letters and numbers of the day.
