Good Burger (1997)

Other mistake: When Dexter is explaining the contract to Ed, Ed pulls out a pen and clicks it. In the next camera angle, Dexter hands him a pen.

Kurt: I want you to bail on Good Burger. You make your sauce for Kurt.
Ed: Who's Kurt?
Kurt: I'm Kurt.
Ed: I'm Ed.
Kurt: I'm aware.
Ed: You said you were Kurt.

Trivia: When Ed tackles the old lady, look closely and you can see that her dentures fell out.

Question: What's the name of the song that the inmates at the asylum are dancing to?
