Hit in the head with a basketball

Has any of you guys get hit in the head with one of your friends because they think that it is funny. Well my friend got hit in the head with a basketball and it is hilarious! But if it was me I wouldn`t be laughing. It all started after a sleepover which I didn`t go because I had better things to do. When they woke up they went to the park to film something. Then all of the sudden my friend made his shirt into a bra and he ran down the hill screaming and my friend hit him the head with a basketball hard. Take a look. http://www.youtube.com/watch?v=q-ZRXg4oCXI
