We recently made the trip to Oklahoma to see family and relax for a little while. On our way we saw some stockyards, I immediately had Davis look to see all the cows.
"Wow, there ARE a lot of cows, why are there so many?" he asked.
Instead of telling him that it's because people eat cows and they kill them, I explained, "Well, cows' poo poo helps plants grow, so they have all the cows so they can get their poo poo to help the plants grow."
"Cool, I wish I could be one of those!!" He said with excitement.
I asked, "A poo poo cow?"
"Yeah, a poo poo cow!"
