Every Sperm is Sacred

The incomparable "Every Sperm is Sacred" scene from Monty Python's Meaning of Live is quintessential Python: Edgy, funny, sacrilegious, insightful, very British, and delightfully over the top.

This one may offend a few people, but if you haven't seen it and have 10 minutes for what some consider one of the funniest scenes in movie history, here you go. (This should be considered NSFW, in case that wasn't evident.)
