A guy goes over to his friend's house, rings the bell, and the wife answers.

" Hi, is Tony home?"
" No, he went to the store."

"Well, you mind if I wait?"

" No, come in."

They sit down and the friend says "You know Nora, you have the greatest breasts I have ever seen. I'd give you a hundred bucks if I could just see one."

Nora thinks 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 the both of them. I'll give you another hundred bucks if I could just see the both of them together."

Nora 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 200 bucks he owes me?"
