This thread went from zero to Hitler in a mere three posts!

zero-to-Hitler 

The elapsed time of a conversation before the subject turns to Adolf Hitler, in much the same way a high-performance car is evaluated at a racetrack.

When I was at a keg party in Santee, this scrawny dude with tatts and a bald head went from zero-to-Hitler in four seconds.
