My cousin told me about the new Covid test, the other night, while we were sitting around the fire, knocking back a few beers.

It's named The Thumb Test - stick one thumb in your mouth. Then stick your other thumb up your ass. After about a minute, swap places with each thumb. If your thumb tastes like shit, you don't have Covid.
