A mid 30's guy is grocery shopping, and a 20 something blonde catches his eye. She looks very familiar, but he can't remember where he met her. When they moved closer, she said to him, ""Hi - I think you're the father of one of my children."" The guy freaks out. He says, ""I've only cheated on my wife 3 times - in Vegas 5 years ago, in Orlando 4 years ago, and in Seattle 3 years ago. You look familiar, but I just can't remember. Who are you?"" She says, ""I'm your son's Sunday school teacher.""
