"A fellow was following a truck in " joke
A fellow was following a truck in heavy traffic. Every block or so, when they were stopped at a stop light, the driver of the truck would jump out of the cab with a big stick and bang on the side of the cargo bay. Hed then jump back into the cab in time to drive away when the signal changed. The first fellow observed this for several miles, until he could stand it no longer. The next time the truck driver jumped out with the stick, the first fellow jumped out and ran up to him. "Im sorry to bother you," he said, over the din of the banging, "but I am very curious; could you tellme what you are doing?" Without breaking rhythm, the truck driver replied, "Sure, Mac. Ya see, this heres a six-ton truck but Ive got eight tons of canaries aboard, so Ive gotta keep two ton of them flying all the time so I dont break an axle".
