Must be nice to be Floyd "Money" Mayweather. A few hours ago, the Las Vegas native Twitpic'd a photo of a bet slip from the M Resort in Sin City last night. Apparently, he put 41 stacks on Derrick Rose and the Chicago Bulls to cover a second half spread and wound up taking home a little over $37,000. Not a bad take for a Tuesday night. Congrats, homie. But we've gotta ask: We see all these winning tix you throw up on Twitter, but how many losing ones are you not showing us? Hmmmm.... [via ESPN]
