One day, the wife is alone and the doorbell rings.
She opens the door to a guy.
"Hi I'm Mike, is Tony home?"
The wife replies, "No, he went to the store, but you can wait here if you want."
So they sit down and after a while of silence the friend says, "You know Sara, you have the greatest breasts I have ever seen.
I'd give you a hundred bucks just to see one."
Sara thinks about it for a second and figures, what the hell - a hundred bucks!
She opens the robe and shows one to him for a few seconds. He promptly thanks her and throws a hundred dollar bill on the table.
They sit there a while longer and the guy then says
"That was so amazing I've got to see both of them. I'll give you another 100 dollars if i could just see both of them together."
Sara amazed by the offer sits and thinks a bit about it and thinks, heck, why not?
So she opens her robe and gives Mike a nice long chance to cop a look.
A while later Tony arrives back home from the store.
The wife goes up to him, "You know, your friend Mike came over today..."
Tony thinks about it for a second and says, "Well did he drop off the 200 bucks he owes me?"
