Oh, that reminds me of a story, I helped a friend remove some digits from the expiration date on a condom (using acetone) and dot in new digits with a fine Sharpie. He then managed to exchange the condom for the one in his brother's wallet. Later that week, at his brother's 25th birthday party, he toasted his brother and mentioned "the condom in his wallet must be expired more than 10 years..." Everyone laughed, the embarrassed birthday boy pulled the condom out of his wallet to prove It was fresh and - poof - joke worked perfectly.
