[Ghoulish Delight]

A relatively simple solution for something like a credit card application. Rip it in half, throw one half into one trashcan, the other half into another. Take the trashcans out on alternate weeks. While the story CP linked to is at least plausible (if outrageous), I'm guessing there's zero chance someone using only half of an application to any great effectiveness. Obviously this doesn't work with anything that might have more sensetive personal info than a credit card solicitation, but it does take care of this case.
