Fifty shades of grey ...
Four guys have been going on the same golf trip for many years. But this year, Ralph's wife puts her foot down and tells him he isn't going. He winds up calling his buddies and tells them the bad news.
Two days later, the three other guys arrive at the resort to begin their yearly golf getaway... and of all things, they find Ralph sitting there with his clubs already setup on his cart.
"Dang Ralphie boy, how did you talk your missus into letting you go?"
"Well, yesterday evening, after my wife finished reading "Fifty Shades of Gray", she pulled me into our bedroom. There on the bed she had placed handcuffs and ropes! She then told me to tie and cuff her to the bed... so I did."
"Then she said, 'Do whatever you want.'"
