It's never a good idea to snap photos inside an occupied locker room. You might as well break into your teammates' houses and upload Instagrams of them in the shower.
Case in point: Chicago Bears wide receiver Brandon Marshall received a shirt from his alma mater, the University of Central Florida. He promptly wore, photographed and tweeted it to his 750,000 followers. The only problem? Right behind him, a Bear was bare.
Deleting the Twitpic was pointless -- it had already gone viral -- but at least Marshall tried to walk it back:
Sorry about my guy in the back getting dressed in that photo.
— Brandon Marshall (@BMarshall) November 14, 2012
The offending photo was accompanied by the message, "Like a kid in the candy store. Look what was in my package." This would've been way, way more awkward if the currently unnamed teammate had been facing the other direction.
