#1: The Swiss Spaghetti Harvest
spaghetti harvest In 1957 the respected BBC news show Panorama announced that thanks to a very mild winter and the virtual elimination of the dreaded spaghetti weevil, Swiss farmers were enjoying a bumper spaghetti crop. It accompanied this announcement with footage of Swiss peasants pulling strands of spaghetti down from trees. Huge numbers of viewers were taken in, and many called up wanting to know how they could grow their own spaghetti trees. To this question, the BBC diplomatically replied that they should "place a sprig of spaghetti in a tin of tomato sauce and hope for the best."
