That '70s Show, Season 7

[Having been given money by Red to buy a jersey, Eric comes back to the stands wearing a Chicago Bears jersey, amidst a sea of Packers fans]

Red:
Eric, how the hell can you wear a Bears jersey at a Packer game?

Donna:
Okay, maybe he doesn't understand why it's wrong. Let me tell you in a way how you can understand. The Packers are like the Jedi, and you're wearing a Go Darth Vader jersey.

Eric:
Uh, that's ridiculous. The Jedi don't play football. They play manu-Ka.

Hyde:
Forman, this is worse than when you wore the Air Supply t-shirt to the Aerosmith concert.

Red:
For God sakes, will you just take the damn jersey off?

Eric:
No. You know what? I like rooting for the underdog, okay? I am the underdog in real life. I like Charlie Brown. I like the little engine that could. I like the Bears.
