From "Porridge", so many of Fletch's one-liners & punch lines that I couldn't possibly list them all. Ronnie Barker's delivery was always spot on and he never looked as though he was playing to an audience (one of the great skills which every comedy actor needs).
A few scenes from "Dad's Army" were also memorable. I was in a German train when the conductor was trying to sort out a problem with another tourist's ticket. "Vot iss your name?" he asked. A lone British voice piped up from the back, "Don't tell him, Pike." Much mirth from the rest of us, which confused the conductor no end.
