Michael Phelps Takes A Fall While Crowd-Surfing

Give this guy a medal for not busting his behind in a crowd-surfing feat gone wrong.

Star swimmer Michael Phelps was partying it up in a Las Vegas nightclub Monday night (Oct. 22) when he and a pal decided to hop into a flotation device and surf through the crowd. If Phelps--who clocks in at 194 lbs. alone--was putting his weight into the boat alone, that still would not be enough for drunk partygoers to carry. Sources tell TMZ he's good but do us all a favor, Phelps, and stick to swimming.
