1. Cut it up, making certain to
a. cut the signature into at least three pieces, and
b. cutting the numbers in half across before cutting them into pieces; then
2. Carefully divide the resulting bits into two piles that are each missing key pieces, then
3. Throw out half the pieces in one week's rubbish; and
4. Throw out the other half two weeks later when there is no chance some weirdo can ever put them back together.
The chance that's not a tad excessive?
