A man had a flat tire on a very cold winter day. He told his girl friend he'd have it fixed in no time. However as it was very cold his hands kept getting cold. He asked his girl if he could put his hands between her knees to warm them.
She said that would be allright. After getting his hands warm he went back to fixing the tire but it was so cold he could not continue so he again asked his girl if he could warm his hands.
She again said it would be allright. When his hands were warm he went back to fixing the tire once more. But before he been out there five minutes or so he again asked her if he could warm his hands.
His girl asked "Honey don't your ears ever get cold?"
