I can’t entirely recall what this sketch from Stewart Lee’s Comedy Vehicle was about, but I think it may have been something to do with Chris Moyles:
When it comes to lavatory visits, by the way, I can usually last a few drinks before going. But when you do decide to visit the boys’ room, that’s it. It’s all over. As Comedy Dave says, ‘once you pop, you just can’t stop’.
Thanks to Paul Rogers for reminding me that it was a skit revolving around Chris Moyles’ autobiography being described as “a good toilet book”!
