Pigeon Bone Problem

Okay, so basically, the joke is saying that pigeons are annoying because their bones get stuck in your teeth. Now, I know you're not the sharpest tool in the shed, but even you can understand that it's not normal for pigeon bones to get stuck in your teeth. I mean, do you even know what pigeons eat? They mostly eat seeds and berries, not your teeth. You probably floss with barbed wire, you animal!
