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.
