|      Jokes You Can Tell in Class    There was a man driving down the road behind an 18 wheeler, at    every stoplight the trucker would get out of the cab, run back and    bang on the trailer door. After seeing this at several intersections    in a row the motorist followed him until he pulled into a parking    lot.        When they both had come to a stop the truck driver once again jumped    out and started banging on the trailer door. The motorist went up    to him and said, "I don't mean to be nosey but why do you keep banging    on that door?"         To which the trucker replied, "Sorry, can't talk now, I have 20    tons of canaries and a 10 ton limit, I have to keep half of them    in the air all the time!"     |
