So...I've seen some threads about individual things from Monty Python, but I've tossed around in my head what it might take to forge a whole MP system for gameplay of absolute silliness.

What would the base classes be? Old Lady (in drag), Bruce, Kniggit, Repressed Peasant?

I know there would be some skills like: Silly Walk, Ride Coconut Horse, others?

Spell: Cartoon Foot. When cast, a giant cartoon foot descends from on high and squashes the intended target, no save.

Bring on the silliness.
