Hmm. Preservatives.
My siblings and I have been playing a similar game for the past 20 years, although not with a hot dog. One of them found this unlikely decorative...thing...at a tag sale. Its a lucite cube with a fake rose inside. Plug it in and wind it up, and the rose slowly spins and lights up with multi-colored fiber-optics, while "To Dream the Impossible Dream" plays on its internal, infernal music box. Damndest thing you ever saw. Whoever receives it as a secret gift at Christmas MUST display it in a prominent place in their home for the next year (or at least when one of the other siblings comes to visit). The recipient is also teased unmercifully by siblings, spouses and children. Hey, it may be ridiculous, but it keeps us laughing, and adds some suspense to Christmas.
