Bigfoot

Bigfoot is a legendary beast said to live in a forest. Only some people believe in him and most who do are broke. Bigfoot was eventually found by Fry and the Park Ranger who wanted to chop off his feet as proof he exists but was stopped by Lrrr. The Park Ranger did however, get photos and some of his hair.

Trivia

 * Bigfoot is mentioned in the title caption for "Kif Gets Knocked Up a Notch".
 * Professor Farnsworth was going to mention that Bigfoot is head of the FBI in "Teenage Mutant Leela's Hurdles" until the writers remembered the events in "Spanish Fry" and replaced him with the Tooth Fairy.
