I think the world record for bad ideas came from a certain world record attempt.
I came across a book that described how back in the 20s and 30s (my google fu has failed for fact checking my memory on this), the method for breaking the motorcycle speed record was to strip down to the equivalent of speedos, grease up the body with axle grease, then lay flat on one's stomach on the seat of the motorcycle, hands forward on the handlbars, feet straight back -- all of this to increase aerodynamic efficiency. They would then hit speeds of 160mph+...
On the Bonneville SALT flats.
When one fellow wiped out this way, the only record he set was for Epic Road Rash.

They stopped doing it that way after that.
