The humor of Monty Python can be appriciated on multiple levels, on the surface it seems to be merely mapcap zanieness (and even on that level its brilliant) but deeper you can find some biting satire.

Of course most of it is wonderfully, and unapologeticly silly. That's why its so brilliant. Like all great humor its the sheer unexpectedness of some of the routines and the nigh- insane way people behave. It's not supposed to be complex, its supposed to be funny and it succeeds wonderfully.
