Brie-fly. (From the late 70s?)

It's a Monday - a rather hot and unproductive kind of Monday.
"Suzi, come home right now! Get out of that pool and come home!"
That's the neighbor, calling her kid. Her brat. Swimming in my pool. Well, Arthur's pool. Arthur J. Stanley. He's the owner of the house I live in. He doesn't like the neighbor's kid, 'cause she's "spoiled rotten." I know these things because I'm the Brie-fly.
What kind of name is that? Who named me? I may have named myself. It doesn't matter.
I'm the Brie-fly.
Yes, it's an awfully hot Monday...
