"Where'd you get that fish?"

Overheard conversation during an after-camp play date at my house yesterday afternoon:

friend: "Oooo. You have a fish."
W: "Yup."
friend: "Where's his mommy?"
W: "Don't know."
friend: "Where'd you get him?"
W: "At PetCock."
friend: "Um."
W: "Wait. I think it's Petco. Yes, yes. Petco."

Yes. Petco.
