Mickey Mouse is one of the world's best known cartoon characters, created by Walt Disney and Ub Iwerks. He made his theatrical debut in Steamboat Willie, which has the distinction of being the first cartoon short with fully synchronized sound. Mickey eventually became the face of The Walt Disney Company, and continues to be used in various projects for the company.
Fred Moore, one of the key animators on Mickey, described the character in a 1930s analysis sheet for studio artists:
“Mickey seems to be the average young boy of no particular age; living in a small town, clean living, fun loving, bashful around girls, polite, and as clever as he must be for the particular story. In some pictures he has a touch of Fred Astaire; in others of Charlie Chaplin, and some of Douglas Fairbanks, but in all of these there should be some of the young boy.”
Throughout the years, Mickey — often teamed with his friends Donald Duck and Goofy — has appeared in hundreds of productions in all forms of media, some of which most notably include Fantasia, The Mickey Mouse Club, and Mickey's Christmas Carol. He is also a permanent fixture in the various Disney Parks around the world, and is often reinvented to keep up with an ever-changing entertainment culture.
Jim and Mickey
Jim Henson was a known admirer of the works of Walt Disney and occasionally spoke of Mickey when discussing or even developing his own characters. Caroll Spinney recalled that when he asked Henson how Big Bird should sound, the latter said "maybe like Mickey Mouse's pal Goofy." Designer Kermit Love later compared the bird and the mouse, claiming that "Like Mickey Mouse, he never gives in to violence."
Kermit the Frog, as the most iconic Muppet and the leader and "straight man" of his troupe, has often been likened to Mickey, and Henson himself compared the two, not as personalities, but as similar abstractions. He discussed how Kermit became "a bit rounder, a bit more froglike. As a parallel, Mickey Mouse looks nothing like a mouse, but he fits into that category. I mean, if nobody ever said Mickey Mouse was a mouse, we wouldn't know what he was, would we?" Henson even kept a Mickey figurine on the fireplace mantel in his office.
- Kermit made a guest appearance on The Wonderful World of Disney (NBC) in 1978 to celebrate Mickey's 50th birthday.
- Mickey (voiced by Wayne Allwine) met Kermit and the Muppets in the 1990 special, The Muppets at Walt Disney World. Kermit remarked that he and the mouse already knew each other from an organization called FASA: Fictional Animal Stars of America.

- In the "Muppet Campaign" sketch produced for Good Morning America in 1992, Miss Piggy and Gonzo field questions from Howard Straighttalk in a mock debate for a Presidential election. Piggy is distressed that she's asked about such difficult topics as unemployment and the national debt while Gonzo got what she describes as a "Mickey Mouse question." Entering from off stage, Kermit butts in to attest that Mickey Mouse is a friend of his, "and I assure you, that question was no Mickey Mouse."
