A man feels lonely one night, so he calls an escort service. When the girl arrives, she’s the most beautiful girl he’s ever seen. He asks her for a blowjob. She smiles. “All right baby, I give the best blowjobs in the country. There’s just one thing: I can only do it in the dark.” The man gets pretty excited. He sits down on his armchair and turns off the lamp next to him, plunging the room into darkness. He hears some fumbling, and pretty soon she’s going at it. She’s right; it’s the best blowjob in the country.
The next day he calls her again and asks her to come over. He sits back in his armchair and turns off the lamp. It’s better than the first time. He can’t believe how good it is. He wonders how the hell she’s doing it. So the next day he calls her again, determined to find out her technique. When she’s blowing him for the third time in darkness, he reaches his hand out to turn on his lamp, but knocks a small round object off the table. He turns on the lamp to find a glass eye on the floor.
