I think that like a lot of verbal jokes, you can set the listener up to expect one thing, then hit them in the faces with something unexpected and generally silly. Two masters of this (in very different ways) were PDQ Bach http://www.youtube.com/watch?v=enT9oAE0TxM
and Les Dawson http://www.youtube.com/watch?v=WWDphFwocAM.

On the other hand, there's always the "funny noises" school. The masters here are Perry & Kingsley http://www.youtube.com/watch?v=ZoeA2eVpuVo.

Have anyone any idea about the world's best funny Music!
