Answer: we have no idea. But we do know that Josh Weintraub -- the Bear Stearns expat recently appointed to the board of directors at troubled lender Residential Capital LLC -- has one hell of a right hook. Apparently, at some point in the past, Weintraub got in the ring (for charity, natch) with Shane Kinahan at Goldman Sachs. And Weintraub kicked some serious Goldman tail, to some strong profanity and chants of "Bear Stearns" from the raucous crowd. Something tells us Goldman's laughing now. But we digress. This video is priceless - and we thought it was a fitting introduction of ResCap's newest board member, given that the company he's now helping direct is in for the fight of its life.
