I can't think of anything in the "message in a bottle" theme right now, but when my bf's parents got married, someone gave her mom a set of cookware with an unlimited warranty, stipulating that no matter what happened to the cookware, it would be replaced.
She wasn't a very good cook back then, so she ruined the first pot she ever tried using and told me that one of the best wedding gifts she'd received was that "unlimited warranty" on her pots and pans
