Speaking of the old daze, at the risk of defiling a perfectly (practically) decent thread with a real (ahem) engineering joke... a REAL OLD one.....

Engineer vs mathematician in a race (males, of course, as the joke is THAT old). Constraints : each time the whistle is blown, contestants can only advance to the halfway point between their position and the finish line, at which, lies a naked, voluptuous maiden (ditto).

At first whistle, the engineer dashes to the first halfway point while the mathematician rolls on the ground laughing. When asked why he is not competing, the mathematician replies, "Any true scientist knows that if you only advance halfway on each leg of the journey, you will never reach the journey's end! It's simple mathematics!"

When the engineer is asked why he is competing, given the logic of the mathematician, the engineer replies, "For all practical purposes, I'll get close enough to end the journey."

With apologies to Dr. Ira M. Beattie, Professor Emeritus, UNB for my liberties with his original joke, upon which the above is based. OK, I'll F off now.
