Favourite Young Ones cutaway sketch?

What's people's favourite random scene that has no bearing on the plot whatsoever?

For me I really like the idiot policemen ("she's annoyed with me ever since I made fun of the Pope." "That's stupid, you know she's a Catholic." "Yeah, but I didn't know he was".)

And probably the spies in the hut scene in Nasty because there is something that's genuinely disturbing about it to me that I can't put my finger on (it's not the man in agony covered in blood)
