In a suburban kitchen somewhere...

Mom begins mixing a batch of brownies.

Hormonal teenage girl, hearing spoon tapping bowl as the eggs get mixed into batter calls from living room, "Mom? What are you doing?"

Mom takes bowl to doorway of living room, and tilting it toward aforementioned hormonal teen says, "Does this give you an idea?"

And teen says, "Ohmygod. Mom, you're my hero!!"

Mom then puts the batch of brownies in the oven, and delivers a teaspoon full of batter to teen in living room.

Teen is very happy.

I, er, Mom says something like, "I could have saved all that batter for myself, you know."

And teen replies, "If you had, I'd have run you over with my menstrual cycle."
