In "Be My Baby", Heckel and Dieter playing soccer... or rather, Dieter trying to play with Heckel and Heckel becoming increasingly annoyed about it.
Heckel: Ow! Sonova... after getting hit in the face with the soccer ball
Dieter: Hey, nice header!
Heckel: Did I look like I was ready to you!?
Dieter: Hey! Remember what I said, you can't use your hands! That's a yellow card.
Heckel: I'm throwin' this into traffic if you mention the rules one more time!
Dieter: If you keep talkin' like that, you'll get a red card.
Heckel: Shut up!
