A tourist climbed out of his car in downtown Washington DC. He saw a man standing near the curb and asked ""Listen I'm going to be only a couple of minutes. Would you watch my car while I run into this store?"" ""What?"" the man huffed. ""Do you realize that I am a member of the United States Senate?"" ""Well no"" the tourist said ""I didn't realize that. But listen I'm really in a bind so I'm going to have to trust you anyway.""
