Husband and wife are closing up their Camplite, getting ready to leave camp and head for home. After checking all the tires, he asks his wife to help him check the lights. She says OK, gets behind the wheel, and has her hand on the turn signal. Husband goes in back of the Camplite, and tells his wife - yes, it's working - no wait it isn't - no wait it is - no wait it isn't...
LOL. Good one.
