A truck driver is cruising along when he spots a little yellow man standing in the middle of the road, crying. He brings the truck to a standstill, rolls down the window, and asks the little man what's wrong.

"I'm yellow, I'm from Venus, I'm gay and I'm hungry," sobs the little man.
"Well," says the trucker, "I can offer you a cheese sandwich, but that's as much as I can do."
So he passes a sandwich to the little man and drives off.
 
A bit later he has to stop again, because there's a little red man in the middle of the road, crying. So he comes to a halt, rolls down the window and a bit more impatiently - asks the little man what the matter is.

"I'm red, I'm from Mars, I'm gay and I'm thirsty," the little man bawls.
 
So the trucker says, "I can offer you a can of Coke, but that's as much as can do."
He hands a tin of Coke down to the little man and drives off.
 
A little further on, the trucker spots a little blue man in the middle of the road. Really annoyed now, he stops, rolls down the window and snaps,” Yes, you little blue moffie, what planet are you from and what the f...k do you want?"

 And the little man answers, "Your driver's license, please..."
