i went to antz brothers wedding 2 weeks ago and his best man did a proper funny bit, dont know if its common thou like....
he said the bit bout him havin all these girlfriends blah blah, and that he used to sneak em in the back door at his mums house, but he wud give each of em a key to let themselves in and out. so he said now he's married, cud anyone with a key please return it so his mum can sleep at night. so all these girls got up and went to the stage and handed a key over. was well funny at the time. even a bloke had one!
