A guy goes over to his friends house, rings the bell.
The wife answers the door.
"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 Sara, you have the greatest breasts I have ever seen. I'd give you a hundred bucks if I could just see one."
Sara 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 100 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 100 bucks if I could just see the both of them together."
Sara thinks about this and says what the hell opens her robe and gives Chris a nice long look. Chris thanks her and throws another 100 bucks on the table then says he can't wait any longer for Tony 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?"
