There's nothing like hearing Bon Jovi in a bar.  Everyone knows the words, and your inebriation leads you to believe your singing voice is far better than it truly is.  Now take a look at Bon Jovi playing "Wanted Dead Or Alive" with Charlie Weis and Bill Belichick.  It's...interesting, to say the least.  Obviously Chuck and Bill don't have the greatest singing voices, but the fact that they intiate the universally horrible "clapping in time with the music" situation really makes this great.

It's funny because Notre Dame and Patriots fans will be like "See?  These guys are the best!  They rock out with Bon Jovi!"  And haters of those teams will be like "They fucking suck at singing."
