Super Troopers (2001)

Other mistake: In the shot where Ramathorne is at the gun range, about to shoot Mac in the bullet proof cup, he is talking to Foster and Rabbit about how they are going to get in to the Spurbury Police Lockup. If you watch him draw his gun, he moves his other hand down to chamber a bullet, the sound effect is heard, but he never actually pulls the action back on the gun.

[Having pulled over a speeding driver.]
Mac: All right, how about Cat Game?
Foster: Cat Game? What's the record?
Mac: Thorny did six, but I think you can do ten.
Foster: Ten? Starting right meow?
[They go up to the car.]
Driver: Sorry about the...
Foster: All right meow. Hand over your license and registration.
[The man gives him his license.]
Foster: Your registration? Hurry up meow.
Driver: [laughing.] Sorry.
Foster: Is there something funny here boy?
Driver: Oh, no.
Foster: Then why you laughing, Mister... Larry Johnson?
[Foster stares at him.]
Foster: All right meow, where were we?
Driver: Excuse me, are you saying meow?
Foster: Am I saying meow?
Driver: I thought...
Foster: Don't think boy. Meow, do you know how fast you were going?
[The man laughs.]
Foster: Meow. What is so damn funny?
Driver: I could have sworn you said meow.
Foster: Do I look like a cat to you, boy? Am I jumpin' around all nimbly-bimbly from tree to tree? Am I drinking milk from a saucer? DO YOU SEE ME EATING MICE?
[The man is uncontrollably laughing.]
Foster: You stop laughing right meow!
Driver: [Stops and swallows hard.] Yes sir.
Foster: Meow, I'm gonna have to give you a ticket on this one. No buts meow. It's the law.
[Rips off the ticket and hands it to the man.]
Foster: Not so funny meow, is it?
[Foster gets up to leave, but Mac shakes his hands at him, indicating only nine meows.]
Foster: Meow!

Question: What is the name of the piece of music that can be heard playing in the German couples' Porsche before Rabbit and Thorny pull them over?
