The only plumber in Glasgow to charge reasonable fees died and was sent to Hell by mistake. Eventually it was realised in Heaven that there was an honest Glaswegian plumber in the wrong place so Saint Peter telephoned (on the hot line) to Satan.
“Have you got an honest plumber there?”
“He’s ours, so can you send him up?”
“You can’t have him!”
“Because he’s the only one who understands air conditioning. It’s really cool down here now.”
“Send him up at once,” shouted Saint Peter, “or we’ll sue.”
“You’ll sue?” laughed the voice at the other end. “And where will you get hold of a lawyer in Heaven?”
