It appears that the US U.S. Fish and Wildlife Service made a tiny error on the new Migratory Bird Conservation and Hunting Stamp (Duck Stamp), which is must be carried for all duck and waterfowl hunters. It costs $15.00, and proceeds go to acquiring and protecting wetlands for said waterfowl.

That would be fine, except for the fact that the most recent version of the self adhesive version of the stamp contains a serious misprint

The correct number, 1-800-STAMP24 (1-800-782-6724), is for people wishing to order additional duck stamps. Levin said two digits of the phone number are transposed on the card that holds the self-adhesive version of the stamp. That incorrect number, 1-800-872-6724, translates to 1-800-TRAMP24. Callers to ‘Intimate Connections’ [a phone sex service] are warned that they must be 18 years or older before proceeding.

This gives the phrase F@#$ a duck a whole new meaning.
