Homer: Thanks! It looks- Hey, wait a minute! Just because I'm wearing pink doesn't mean I'm some kind of pink doughnut-eater! Although it is tempting.

Mr. Burns: Judging by his outlandish attire, he's some sort of free-thinking anarchist!

"Michael Jackson": Hi, I'm Michael Jackson, from the Jacksons.
Homer: I'm Homer Simpson, from the Simpsons.
