Background[]
In "City on the Edge of Forever (Flashbacks)", Ms. Crabtree, in an attempt to seek help for her trapped bus, ends up in a club where Carrot Top is performing. Ms. Crabtree insults Carrot Top, much to the amusement of the audience, and gets recruited by an agent. She is eventually featured in The Tonight Show with Jay Leno, insulting the audience only to be responded with laughter.
In "Fishsticks", Jay Leno shares the Fishsticks Joke to the audience, in a similar manner to Jimmy Valmer, with two men within the audience throwing up.
