If its one thing I know, Travis' tend to be smart, good looking, and able to store vast amounts of pointless trivia in their head. But it doesn't take a Travis to be able to calculate simple distance math or know the sun is 93 million miles from Earth.
Apparently this is a somewhat popular prank... although I've never heard of it. It seems pretty simple (and clever) too. You just take a Cornish game hen, which looks like a little chicken or turkey, and stick it inside your turkey before you cook it.
