Is there anything more emo than a bloodstain?

I'm being led to believe that the bloodstain pictured over at Chicagoist is the result of Pete Wentz's latest public tantrum. It's unclear from the account whose blood we're really looking at here, but does it matter?

From what we could see, Pete decided to have a “word” with a heckler who teased him about his relationship with Ashlee Simpson on his way out, and the shit (and a well-aimed beer bottle) then promptly hit the ‘fan.’ It wasn’t immediately clear what Wentz down, but we caught a glimpse of Pete on the floor with the other dude on top of him

Really great punnage from Chicagoist's writing staff, no?
