So, these four guys had, for years, taken a weeklong backpacking trip every year. This year, Fred had some bad news for his buddies: "My wife says 20 years of these trips is long enough, and that if I waste another week of vacation on one this year, we're finished. So, I guess I won't be going."
The other three were disappointed, to say the least, but went on the trip without Fred. When they arrived at the trailhead, there was Fred, pack on his back and poles in his hand!
"What happened? How come you're here?" they asked.
"Well," said Fred, "my wife was reading Fifty Shades of Gray. One night, she pulled me into the bedroom and pointed to some ropes and handcuffs on the bed. She told me to tie her to the bed, so I did. The she told me to do whatever I wanted."
That reminds me of the engineering student walking through the quad and seeing his fellow engineering student on a bike. He asks, "where did you get that bike." His friend reply's, "I was walking along and this cheerleader rides up to me, throws down the bike, rips off all her clothes, and says 'take what you want'."
"Good choice," his friend reply's, "I doubt the clothes would have fit you."
