The other night I was watching the Phillies play the Giants when something caught my eye--and turned my stomach. The announcers were discussing Tim Lincecum, so they put a camera on him. While filling the screen with his face, he blew his nose into his hand, then gobbled up his nose's leavings:

I don't know. The camera did cut away for a few seconds, but it's still pretty clear what he was up to as he assumed nobody was watching. All I can say is: ewwwww!
