There was a man who was very happily married, but, every birthday he would have the same fantasy request for his wife: He wanted a threesome, and every year the wife says no.
This continues on for several years, until finally the wife has enough and finally agrees.
“Fine Sam, yes you can have your damn threesome. Who do you want it to be with?”
George quickly responds with... “Well, do you remember Sarah who works in accounting at my office?”
“Yes, of course.” the wife responds.
“Well, with her." Said Sam, "and one of her friends.”
