(A customer buys an African clawed frog for her son. After bagging it, I bring it to the register. It swims around in the bag for a second as I set it down.)

Customer: “Oh my god, what is it doing?”

Me: “You mean swimming?”

Customer: “Why did it do that?”

Me: “It was probably coming up for a breath.”

Customer: “It breathes?”

Me: “Yes.”

Customer: “So, it’s not a fish?”
