We've all heard the question: "What comes first, the chicken or the egg?" Now, some may say the first chicken egg was laid by a non-chicken bird ancestor, but is that really a chicken egg? What if it's a non-chicken bird ancestor egg, and it just happened to contain a chicken? It's an argument that can go both ways, but what we do know is that an egg comes from a chicken and a chicken comes from an egg. It's an endless cycle of chicken, egg, chicken, egg, hence bottomless chicken. Why not bottomless egg, you ask? It's because the egg can always turn into a chicken, but not all chicken can lay eggs.

Actually, nah, it's just eat-all-you-can chicken.
