There is an episode of Spongebob Squarepants where our hero witnesses a comedy show at his place of employment (the Krusty Krab, for those who are unaware). After seeing the show, he decides that he also wants to partake in that rush that comes with performing in front of an adoring audience, people applauding and laughing and generally in favor whatever he was going to do.
When he tried his original act, it fell flat. No one wanted to hear what he had to say. Finally, he decided to make fun of the facial features of his best friend, a squirrel.
