Har har har. I read this in (what I assumed to be old) magazine a couple days ago, it's not so much new.. it happened on Dec. 15.. anyway, http://www.mp3.com/updates.php?artist_id=4762&article_id=31247
is the full story, but apparently Rod Stewart knocked a guy out with a soccer ball.
SCORE! It made me chuckle, thought I'd share.
Edit: Fixed the link!
