Yeah, Monty Python is great. Although it's just for laughs, most of their work actually bears a good message. One of the best pieces of art that ever got in the mainstream.
I love that scene Monty Python also made some well fun parodies on communism too. http://www.youtube.com/watch?v=vZ9myHhpS9s I like this one - And it's clear that there's a message to the madness too
