You said the game was in the bag before it even started. I don't have that arrogant complex you have, that's all. Call yourself a Nostradumbass and move on man. When you said what you did, you should have realized the consequences if you were wrong, but even moreso, if the EXACT OPPOSITE happened, which is exactly what happened. That's why it's so classic, because now you're trying to play it off with an attitude, it's funny.
Just have a sense of humor and admit you were way off. It's funny if you don't let it bruise your ego.
