I think he may thrown the shoe because he was angry he wasn't there to debate legalising same sex marriage. Would certainly explain his feminine(i'm the one who takes it)throw. NOT THAT THERE IS ANYTHING WRONG WITH THAT Ps: i know it's not nice to assume the man is on the other side of the fence to me, but it gives me comfort to think that he is because the only other alternative is that he's on my side of the fence. I'm pretty sure that not many people want to be on his side of the fence :)
