LOL @ the participation medals on the wall. 
Those are his Olympic Gold medals.
The IOC gave them to him as a token of appreciation, for allowing others to participate and have a chance to win.
hanky has been dominating every sport since he was 3 months old and was a super star swimmer.
It was time for new athletes to have a chance.
On the other wall there are 117 black belts, from all the dojo's he's stormed over the years.
Word on the street is the minute he enters a dojo, they all bow and hand over their belts as a sign of respect to the greatest grappler/boxer/wrestler/accountant this earth has ever seen.
