HAHA! Yeah there should be like a feature that you can turn on or something. In FIFA07, there is a feature that lets 'weird sounds' happen. If turned on, the crowd says weird stuff, ball kicks sound weird.

Should be stuff like heavyknockout911 said. How funny would it be if your fighting say Tyson vs Lewis as example:

Crowd Guy 1: "YEAH TYSON!"
Crowd Guy 2: "Stuff Tyson! Lewis' Smashin Him!"
CG 1: "OH WHAT FOOL?!"
CG 2: "BRING IT HOMES!"

Full smash each other in the background.

Haha
