If you want to do this and be funny, you have to step up your game and put jokes into a context that makes sense to the recipient.
Let me help you out:
1. Utah is not big possum country. Making a joke about possum roadkill is meaningless to us. I don't think I have ever seen a dead possum on the roads in Utah. Of course, to know that, you would have to take off your coon skin cap and buckskin pants and put on some real clothes and venture out of the trailer park.
2. In Utah, we really don't have a lot of roadkill on the highways period. And most people make enough money that we would not consider roadkill to be dinner. Unlike Tennessee, the legislature does not see a need to enact laws to govern use of dead animals found on the road. The actual Tennessee law states: "Wild animals accidentally killed by a motor vehicle may be possessed by any person for personal use and consumption.'' I wonder what sort of "personal use" the Tennessee legislature was concerned about? How "personal" are we talking here? Sounds like Tennessee and Wyoming have some things in common.
On a more sincere note, I was truly saddened to hear about the little kids that were trampled and died at the family Christmas party in Tennessee. When the Hostess yelled "Pump-kin!", she was so shocked to see all the old men grabbing one of the too-young girl cousins and heading for the bedrooms, that she couldn't even get out the word, "Pie!".
