Changing Number Terms

In a recent contest in The Washington Post, readers were asked to take an expression using a number, add or subtract one, and create a new definition:
The Year 2001 Problem: How to find jobs for all those programmers hired to solve the Year 2000 problem.
Catch-23: Complete the previous catch before proceeding to this step.
Fortune 501: Levi Strauss makes the list, but just by the seat of its pants.
Motel 5: If you're not there by midnight, they turn off the light.
Dressed to the Eights: Impeccably attired with white socks.
Six Brides for Seven Brothers: Someone's gonna get hurt!
Snow White and the Eight Dwarfs: The title, before they expelled Gassy.
Five Eyes: Other kids can be so cruel when you are Siamese twins, and one of you is wearing a monocle.
665: The mark on the forehead of Satan's slightly less evil brother, Ralph.

A woman went to a discount store to purchase several items. When she finally got to the checker, she learned one of her items had no price. She thought she'd die of embarrassment when the checker got on the intercom and boomed out for all the store to hear, "Price check on lane thirteen. Tampax. Supersize." As if that wasn't bad enough, the person looking for the price misunderstood the word "Tampax" for thumbtacks. In a businesslike tone, a voice boomed back over the intercom, "Do you want the kind you push in with your thumb or the kind you pound in with a hammer?"
