When an UK man was asked to be the best man at a friend's wedding he agreed that he would not pull any pranks before or during the ceremony. Now the groom wishes he had extended the agreement to after the blessed occasion as well. The best man snuck into the newlyweds' house while they were away on their honeymoon and placed a pressure-sensitive device under their mattress. The device now automatically tweets when the couple have sex. The updates include the length of activity and how vigorous the act was on a scale of 1-10.
