My brother used to jump off the roof of our two story house into the pool all the time. I was too smart (or chicken ****) to try it. I did laugh my *** off at a friend of mine who saw him and said let's go do that. I told him to go ahead but I wasn't having any of it. He gave me hell about it. Then he climbed onto the roof, walked over to the edge, stood there for about 5 minutes, then climbed back down. Over 20 years later, I still give him hell about that.
