It's a nice way to show people that you watch House MD(the big sign on the ball is pretty hard to miss).
the only thing i dont like about this is the obvious logo. it signigies that it is from House but now it doesnt look like the one from the show. maybe if were lucky they will put the real one up for auction for charity when the show ends. thats what they do with the canes every time house gets a new one (or so i hear) as for why he has a dog toy why not? hes house!! if we could explain him the whole show would end
