Futurama - Bender's Gaydar

Amy: So what do you think of that guy by the bar?

Leela: I don't know. Maybe?

Bender: Forget it, he's gay.

Leela: What? How can you tell?

Bender: I just know these things. I've got what they call gaydar.

Leela: There's no such thing.

Bender: No? [He pulls out a machine with a small antenna on it from his chest cabinet. The antenna swivels around.] OK, I got a lock on him. [The machine beeps.] Yep! He's gay!

Amy: Are you sure?

Bender: Definitely. Unless I'm getting interference from a gay weather balloon.
