My husband used to have a roommate whose family would make Christmas cookies with rude sayings on them. When a family member would arrive, they'd say "There's a cookie there with your name on it," and the person would see that the cookie said "jerk" (or worse.)
This has now become a tradition between my husband and myself. We basically try to see who can come up with the most creative phrase for the hearts. This year my kids are old enough to understand the concept, so we let them in on it. I think that one of them came up with "restraining order," actually. Ah, family fun.
