Fishing and cricket fans will love this. A short recording of Christopher Martin-Jenkins 'corpsing on air after making an unfortunate fishing analogy on Test Match Special (I love fishing but, with the exception of golf and Formula 1, cricket is possibly the most boring pursuit on earth).
As 'corpsing' goes, I still reckon the best one ever is the delightful Charlotte Green on Radio 4's Today show. I defy anybody to listen to that and not find themself smiling...
