Bar fights and athletes? Not so weird.

Karaoke bar fights and athletes? Now, that's a whole other story.

Liverpool striker Craig Bellamy allegedly hit his teammate John Arne Riise in the legs with a golf club -- repeatedly, mind you -- while the team was training in Portugal for a Champions League match against FC Barcelona.

And according to one source, the reason behind the alleged assault was that Bellamy was still angry at Riise because Riise had rebuffed Bellamy's attempts to drag him up on stage for a karaoke competition.
