I've seen one but can't find it online. Anyone know where to get one of these?

 

Not sure exactly what you mean since you don't include a picture. But if you're talking about the kind of home dec some people hang from the edge of the roof or the chimney, google "hanging santa" or pick one up at Walmart and afix it to your spare.

Seeing something like that would be worth a chuckle, I suppose.
