A guy stumbles out of a hotel in Las Vegas. Down to his last few dollars, he
 needs to get a cab to the airport for his flight home. Going up to the only
 cab in front, he asks the driver how much it is to get to the airport. The
 driver tells him, $10. Reaching into his pocket, and finding only $8, the guy
 pleads his case. The cabby screams at him to get the fuck out of his cab,
 calling him a freeloader and other vile things. He hitchhikes to the airport,
 fortunate to get a ride, and heads on his way.
 
 Six months later, the same man, flush with success at the gaming tables,
 leaves with a pocket full of money, intending to catch a cab to the airport.
 He sees the *same* cabby, 3rd in line in front of the hotel. He heads to the
 first cab, jumps in and says to the driver, "Say, I need to get to the
 airport, but how about you giving me a blowjob, too. I'll pay you $100". The
 cabby starts swearing at him, "Get out, you pervert!" So the guys goes to the
 second cab in line, tells about needing a ride to the airport, and makes the
 same $100 offer for a blowjob. He is promptly thrown out of the second cab as
 well.
 
 He goes back to the third cab, jumps in and says only "Take me to the
 airport." Then, passing the first two cabs, the gambler smiles brightly, and
 gives them a big thumbs up!!!
