Inexplicable gift

I received an inexplicable gift last night. One of my opponents went all in on a mere pair of queens, while I had a full house. The queens were on the board; all my opponent had for hole cards was K 3 offsuit. My hole cards were a third queen and a second ace, as there was one ace on the board. I won a pot worth $84k, $40k of which came from my generous opponent. I guess he was trying to buy the hand with a stone bluff. Not a good idea!
