FOR WOMEN ONLY
So they start going up, and on the first floor the sign reads, "All the men here have it short and thin." The friends laugh and without hesitation move on to the next floor. The sign on the second floor reads, "All the men here have it long and thin."
Still, this wasn't good enough, so the friends move up to the third floor, where the sign reads, "All the men here have it short and thick." This was still another disappointment, but knowing there are still 2 floors left, they move on to the next floor.
On the fourth floor, the sign was perfect. "All the men here have it long and thick."
The women get all excited and are just about to go in when they realize that there is one floor left. Wondering what they were missing, they go to the fifth floor, where the sign reads, "There are no men here. This floor was built only to prove that there is no way to please a woman."
