Funniest movie moment ever

A holiday themed post - or at least as holiday themed as you'll get from me:

This movie clip has the funniest five second moment that I have ever seen filmed. If you've never seen Monty Python's Life of Brian, it is a great satire on the excesses of fanatical religion. The set up on this clip is that Brian has just escaped from the clutches of Pontius Pilate and the Roman centurions in Jerusalem, and he's heading up a staircase. (An incomplete staircase apparently...)
