WSOP 2011 - Winning a Pot with Someone Else's Chips

Darrell Roberts won a nice pot under quite funny circumstances at the World Series of Poker Main Event. Roberts sat down at his table after returning from the bathroom

What he did not notice, however, was that his table (table 308) had actually been moved to the ESPN main stage section during Roberts' break. So, after returning, Darrell started playing at seat 4, table 303, which at the moment incidentally had an empty seat just where Roberts had sat earlier with about the same amount of chips as well. It is no wonder that he immediately leapt into action and won a pot. And this was the moment when the real occupant of the seat appeared, and raged about someone playing with his stack. 

The incident was quickly resolved: of course, the real owner of the seat could not keep the chips Darrell had won him (Darrell took them to his real table at the ESPN main stage). The only person losing anything in this case was the player whose chips were taken by Roberts; no matter how much he complained, he did not get those back.
