Fozzie Bear is The Muppet Show's resident comedian. He's an orange-brown, fuzzy Muppet bear who tells bad jokes, usually punctuated with his catchphrase, "Wocka wocka wocka!" Fozzie's best friend is Kermit the Frog, although they occasionally have differences of opinion.

During the first season of The Muppet Show, Fozzie's monologues usually consisted of Fozzie telling simple setup/punchline jokes, while being heckled by his mother's old friends, Statler and Waldorf. After the first season, most of his monologues relied on gimmicks such as telling jokes on roller skates. A common schtick in many episodes is that Fozzie would attempt to imitate the guest star's most famous act to attempt to emulate their success, only to comically fail completely at the attempt. For instance, Edgar Bergen inspired him to try ventriloquism while stage magician Doug Henninginadvertently convinced Fozzie to try his hand at being a magician.

In Jim Henson: The Works, Christopher Finch wrote: "One of the biggest problems [with the first season] was with Fozzie Bear. Fozzie was crucial to The Muppet Show because he was conceived as Frank Oz's main character, and the success of the show would depend to a significant degree on Frank having the opportunity to display the full range of his virtuoso performance and comedic skills.

"It was logical to have a comedian as a primary character on The Muppet Show, particularly once the Muppet Theater had been established as its basic setting. And given the spirit of the Muppets, it was almost inevitable that he would be a bad comedian. The problem with Fozzie was that his bad jokes and failure to win over an audience provoked more embarrassment than sympathy. For instance in episode 122, Fozzie gets so fed up with the heckling that he demands everyone but true Fozzie fans leave the auditorium. As a result, the seats are left completely empty; even Fozzie's own cousin leaves; Fozzie departs the stage almost in tears.

"Jerry Juhl and Frank Oz gradually transformed Fozzie by building up the positive aspects of his personality. They allowed his perpetual optimism to offset his onstage failures until he became a more rounded character. Fozzie's virtues ultimately made his ineptness acceptable -- and even endearing. So successful was this metamorphosis that he became one of the most popular of all the Muppets."

As Brian Henson notes in a generic Muppet Showintroduction, "Fozzie is always telling terrible jokes, but he's just trying so hard you've got to love him."

As an infant, like many of the Muppets, Fozzie was under the care of Nanny (as seen in Muppet Babies). Fozzie's mother however kept some early home videos of Fozzie and the other Muppets, as shown in A Muppet Family Christmas.

As a kid, Fozzie was raised by his mom and dad, along with his baby brother Freddie. Fozzie grew up right next door to his best friend Kermit and often spent time withhis grandpa. Even as a baby, Fozzie always had an interest in becoming a comedian.

Fozzie remarked at the D23 Expo in 2009 that he originally studied comedy at the Country Bear Jamboree.

Fozzie became a stand-up comic at the El Sleezo Cafe, where Kermit invited him to come to Hollywood to become famous. Fozzie took his uncle's car, which was left to him while his uncle hibernated, and the pair set out for Califonia. However if Fozzie had never met Kermit, he would have ended up becoming a skilled pick-pocket (so good that he could pick the pocket of someone without pants).

However, according to The Great Muppet Caper, Fozzie and Kermit are identical twin brothers and share the same father.
