A man named Chris

This guy called Chris goes over to his friend's house, rings the bell, and the wife answers.
"Hi, is tony home?" he asks.
"No, he went to the store."
"Well, you mind if I wait?"
"No, come in"
They sit down and Chris says, "You know Tina, you have the greatest breasts I have ever seen, I'd give you a hundred bucks if I could just see one."
Tina thinks about this about this for a second and figures what the hell- a hundred bucks. She opens her robe and shows one. He promptly thanks her and throws a hundred bucks on the table.
They sit there a while longer and Chris says, "They are so beautiful I've got to see both of them. I'll give you another hundred bucks if I could just see them together."
Tine thinks about this and thinks what the hell, opens her robe, and gives Chris a nice long look. Chris thanks her, throws another hundred bucks on the table, and then says he can't wait any longer, and leaves.
A while later Tony arrives home and his wife says, "You know, your weird friend Chris came over."
Tony thinks about this for a second and says, "Well, did he drop off the two hundred bucks he owes me?"
