I surely am. There's far more to Bottom than the Tom and Jerry stuff. I don't know about Porridge, but there are a few bits more or less lifted straight out of Hancock's HH, though Galton & Simpson were never cited as an influence...
...and I maintain that there was a genuine attempt by Mayall / Edmonson to develop the characters in Bottom - how successfully being another matter, admittedly.
I have a feeling that Rik 'n' Ade did actually persuade some theatre to cast them in 'Godot', but they weren't very good.
PS. Michael, you can just about ruddy well take back what you said about Emma Bunton, young man.
