A store that sells new husbands has just opened in Perth, where a woman may go to choose a husband.
Among the instructions at the entrance is a description of how the store operates:

1. You may visit this store ONLY ONCE!
2. There are six floors and the value of the products increase as the shopper ascends.
3. The shopper may choose any item from a particular floor, or may choose to go up to the next floor, but cannot go back down except to exit the building!

So the woman goes to the Husband Store to find a husband.

On the first floor the sign on the door reads:
Floor 1 - These men have jobs.
She continues upward.

The second floor sign reads:
Floor 2 - These men have jobs and love kids.
She continues upward.

The third floor sign reads:
Floor 3 - These men have jobs, love kids, and are extremely good looking.
"Wow," she thinks, but feels compelled to keep going.

She goes to the fourth floor and the sign reads:
Floor 4 - These men have jobs, love kids, are drop-dead good looking and help with housework.
"Oh, mercy me!" she exclaims, "I can hardly stand it!" Still, she goes to the fifth floor and sign reads:

Floor 5 - These men have jobs, love kids, are drop-dead good looking, help with housework, and have a strong romantic streak.

She is so tempted to stay, but she goes to the sixth floor, where the sign reads:

Floor 6 - "You are visitor 31,456,012 to this floor. There are no men on this floor. This floor exists solely as proof that women are impossible to please. Thank you for shopping at the Husband Store."

To avoid gender bias charges, the store's owner opens a new wives store just across the street, also with six floors and the same rules.

The first floor has wives that love sex.

The second floor has wives that love sex and have money.

The third through sixth floors have never been visited.
