Are you sure, Mommy?

We went to a dog-themed birthday party this morning and on the way home Logan was pretending to eat out of the dog bowl he got at the party and he said he was a doggy and proceeded to bark. The conversation went as follows:

L: I'm a dog, Mommy.
Me: Really?
L: Yes, woof, woof. Are you a dog, Mommy?
Me: No, I'm not a dog.
L: Are you sure, Mommy?
Me: Yes, I'm sure.
L: (Puts bowl on head) Well, I'm a hat dog, Mommy!
