Perhaps this should fit in the maths thread.
Given that "anything is possible, with the exception of waterskiing through a revolving door", we aim to use scientific method to calculate the actual probability of said occurence. It is presumed, for these purposes, that there is nothing strange in finding a revolving door in the middle of an expanse of water used for recreational sporting activities. Now, lets calculate:
a) the speed of the revolving door
b) the speed of the tow boat
c) the fastening of Bonnie's bikini (clasp or knot?)
d) the speed of Amos' reaction
e) the prevalent atmospheric conditions (e.g. tide, windspeed, current etc.

I'm working on the equation. My maths is terrible.
