Odd

I can't remember where I took this snap...

Another treatment day. So, there was this big bloke opposite me. Friendly enough, but didn't look like he suffered fools gladly. He had some issues with a feeding tube down his nose. Anyhoo, he kept watching episodes of an old TV sitcom (he didn't have earphones, so we also enjoyed the shows too).
Any guesses as to what the chap might have liked viewing? Clue: it involved a Mrs Slocombe's pussy.
