I remember Chris Evans and his mate Dan doing On The Bog sketches on the Radio 1 breakfast show in the 90s. They were in adjoining cubicles.
Chris: Dan mate there's no toilet paper in here can you pass me some?
Dan: Sorry mate none here either
Chris: Oh no what am I going to do?
Dan: Have you got anything in your pocket?
Chris: I'll have a look ... Oh yes a bus ticket.
Dan: That'll do.
Washing their hands later ...
Chris: I hope the bus driver is ok about that bus ticket.
Dan: What you on about?
Chris: Well I had to keep it.
Dan: You what? You put it back in your pocket after you wiped your arse with it?
Chris: Well yes it's a return ticket.
