When they're hostages and you think Rodney's reaching for the sleeping kidnapper's gun - in fact he picks up the ciggies.
The Trivial Pursuit game in The Jolly Boys Outing.
Also let's not forget, at its peak they could do dramatic scenes brilliantly - after Grandad's wake when Rodney has a go at Del for being too upbeat and Del replies he doesn't know what else to do - no laugh points, but gripping and superbly played.
And the triumphant end of the episode where they've been conned by the bloke selling gold chains - for once, everyone comes out a winner.
I agree it oustayed its welcome. Some of the ones after they became millionaires were an insult to the memory of a once great show. Sometimes, programme-makers can't see past a show's success and think it will carry on being good as long they keep bringing it back.
