One for the engineers/mathematicians out there
A 747 was flying into New York from Warsaw, and its flight path took it south of lower Manhattan. The pilot came on the radio and said "If you look out the north side of the jet, you can see the Statue of Liberty." Everyone got up to look and the plane exploded. Know why?
Too many poles in the right hand plane.
OK so you have to have studied engineering to get that one.
But I know you Chem Es out there are rolling on the floor.
