Who: Joe Smith, Retired Baketball Player
Offending tweet: Twitpic (see above)
Consequence: Separation from his wife.
All athletes should know that if you're going to have jumpoffs, at least keep 'em in their place. Joe Smith forgot about this when a groupie of his, Deanna Marie, got out of pocket and posted Twitpics of herself with the NBA baller. Smith's wife, Yolanda, didn't take a liking to this and got into a Twitter fight with Deanna and eventually separated from Joe Smith. In this situation the only winners are the producers of Basketball Wives.
