Hey, I've just thought of another one...
There's an Englishman, an American and a German lost in the desert. They come across a lamp and give it a rub.
Out pops a genie. He offeres to help them out of the desert by giving them a wish each - they can wish for whatever transport they want.
The Englishman wishes for an Aston Martin, so he can drive out in style. An Aston miraculously appears.
The American asks for an Apache helicopter. As if by magic, an Apache arisies from the sand.
The German asks for a pig and four springs. "What???" says the genie. The others just stare at him in wonder.
"I'll have a pig and four springs please," repeats the German. "OK, if that's what you want," says the genie. A pig and four spings fall with a thud and an oink to the ground.
The three friends agree to meet up at a hotel when they get out of the desert.
..... cut to the hotel .....
The Englishman is just parking his Aston Martin, when he hears the buzz of a helicopter. The American lands in the carpark too, and they exchange greetings.
"Where's the German?" askes the Englishman, "Who knows," replies the American, "Probably still chasing his pig around the desert!".
They enter the hotel, laughing, and head for the bar. There, sat drinking, is the German.
"How did
you get here!???" they ask.
"Foursprung Pork Technique," replies the German.
(I guess you need to have seen the old Audi adverts to get this...)
