Who Let the Dogs Out?

Picnicing with friends.
Swarms of children.
And a dog.
A big ole clumsy golden retriever dog.

The husband stands next to the food table (of course) observing a four-year-old boy who is watching the dog run loose and happy around the yard.
The dog is, oh, roughly... larger than the 4-yr-old.

When the dog trots away to the far end of the yard, the husband and the boy look at each other.
The husband says, "That's a pretty big dog, isn't it?"
The boy eyes the husband up and down and replies, "You're the big dog!"

The husband hasn't stopped chuckling.
