Good choice with Billy Connelly - the world was awash with speculation about how Boeing dealt with the age old question of how a 747 could travel 14 hours with 400 people on board and deal with the waste products. Initial speculation was a second 747 trailing closely behind attached with waste disposal tubing. Billy's answer (which appears patently obvious now in retrospect) was the "Jobbie Wheecha" which he described as sort of a ladle on a spring which operated behind the scenes when you flushed the toilet on those BUFF (big ugly fat f****r) aircraft. Simple yet ingenious and it took Scotland's master comedian to reveal this industrial secret. Not bad for an ex shipbuilder.

Once this question was answered, the world's best and brightest minds could turn their attention to hunger, achieving a lasting world peace and why water spins clockwise in the toilet bowl.
