Friend of mine used to be a professional singer, went on tour with Chubby as his warm-up act - he tells this story.
Apparently when Chubby started out he was a little bit risque, but nothing too bad. Then decided to go all-out really blue to make a name for himself. He'd been booked for a gig for some sixth-form school - they assumed he wouldn't be too over the top. Up on stage, he tells his first joke, very blue, there's stunned silence in the audience. He looks over his shoulder, there's a statue of Jesus on the cross hung on the wall behind him. So he says, "I suppose that f*cker died here as well !". Apparently he had to be ushered out of the building pretty sharpish.
