I was watching the introductions to the Home Run Derby last night and thought that I heard this. Chase Utley (who plays for the Phillies) was introduced to the crowd at Yankee Stadium and a round of Boo's could be heard. Chase didn't take kindly to this and said "Boo. F*** You". It was all caught on live TV. They put in a delay shortly afterwards (which was used more than a few times). But if you missed it then you can see it HERE

WARNING!! IT DOESN'T CENSOR IT SO THERE IS A WORD THAT IS NOT SAFE FOR YOUNG EARS AND i'M SURE YOUR WORK DOESN'T NEED TO HEAR IT AS WELL!!

Don't say I didn't warn you.
