When someone tells a joke and then explains the punchline, does it make the joke funnier?
When you’ve made a dumb mistake and someone points it out, is that helpful?
I am reminded of of a scene from John Cleese’s brilliant Fawlty Towers where Basil Fawlty reacts to his wife Sybils’ comments: “Perhaps we can get you on Mastermind; next contestant, Sybil Fawlty from Torquay, special category, The Bleedin’ Obvious!”
