There are two guys sitting at a bar on the top of the sears tower. one guy looks the other guy and say, "hey if u jump off the roof of this building you will fly back in through the 9th floor window". the other guys calls him some obscene names and tells him to prove it. so the guy jumps off, hes falling and whoosh right in the 9th floor window, he gets back to the top and the guy says beginners luck, do it again, so he does it again and this time he flyis in through the 9th floor window again. so the other guy now goes and jumps! hes falling, 10th...9th...8th..7th...6th...5th...4th...3rd...2nd...1st....SPLAT! The bar tender shakes his head at the guy who lived the two falls and says...." damn superman, your an a*shole when ur drunk".
