So once upon a time, in the area I lived, the local country music station sponsored a cow chip throwing contest. You got to take your pick from a literal pile of dung, and threw from a designated spot, and there were people there with tape measures to measure how far you got.

Well, I was an early teenager. I was in line to throw, and I was bragging about how good my cow chip was - how it had this perfect indent for me to grip it, and so on. And the guy standing next to me in line saw what I meant, and offered to buy it from me.

I literally sold a cow chip for 50 cents.

Looking back on it, I suspect he may have had some alcohol...

So, yeah. It's not just peas that people throw in competitions.
