The guy on the right in the,
ahem, pink shirt is Brady Quinn. He's some stud Notre Dame quarterback who was supposed to go in the top five of the NFL draft last week but fell to pick #124 (or something like that.) Anyway, I have no idea what he is doing in this pic other than to describe it as "inappropriate clowning around if you want someone to question your sexuality."
But the expression of the guy in the middle is priceless.
