LOL, Wolfgang! Brilliant point.

I have tried applying the very same technique, the "act of using repetition as a means to transport humour", with at least some success (Shatner, hamsters, Hillary Clinton blow-up dolls, Chongo Chimp, etc). I agree that Shambles is approaching absolute mastery of this art form, and he is doing it elegantly through one simple framework by refining that one framework into endless variations of itself. Clever.

I attribute Spaw's downfall to the tragic mistake of using farts as the central buttress of his humour. This was a great strategic error, because farts are simply, to put it bluntly, not very funny...unless you're a ten year old.

Some find that sort of thing irritating or tedious. Others find it hysterically funny. Observe the great comedians of history and you will find that they almost all used the same technique...repetition of easily recognizable images and scenarios.

Classic examples of comedy by repetition: Abbot and Costello, Laurel and Hardy, Charlie Chaplin, Peter Sellers.
