Two carpenters, Sam Plank, and Harry Nail, set up in business together, sadly Harry Nail died and went to heaven.
While he was up in heaven, Harry Nail won the lottery, and got the privelege to spend 24 hours of absolute freedom.
Harry chose to use his 24 hours visiting his lifelong buddy, Sam Plank.
Sam was delighted to see his old buddy again. He explained to Harry that he'd acquired some considerable wealth, taking over a chain of disco's. "Come on, let's have the crack, come to one of my Discos and we'll party down."
Harry Nail got carried away. What with all the drinking and the whoring...
He turned up at Heaven's Gate three hours late.
"Where you been?" Saint Peter roars. "You're three hours late! And where the hell is your harp?"
Oh shit, Harry thinks.
Then he sings:
"I left my harp, in Sam Plank's disco..."
Fucking terrible I know, but it made me laugh many moons ago.
