I was thinking about classic sitcom scenes with obscure props that make the joke or iconic to the sitcom for example Arkwright's broken till from Open All Hours, or the moose's head from Fawlty Towers, Frankie Howerd's wig that he wore over his real hair or Alan Partridge's corby trouser press.
Would it be fun to make a list and share some favourite sitcom scenes/props that are recurring factors to making the sitcom great?
