Is that a turtle or a terrapin?

Terrapin:

Am I a bad person for immediately wondering how that thing poops?

Ah, memories of dad…

Dad: The meanest animal in the world is the lizigator. It’s a lizard on one end and an alligator on the other.

Me: How does it poop?

Dad: What do you think makes it so mean?
