If you give Colleen a Cookie,
She's going to eat it and ask for another.
Because she is a Cookie Monster, and her Prince Charming makes the most delicious cookies ever.
Then she is going to feel guilty about all the sugar she just ingested.
And so she will eat some chocolate to make herself feel better.
After that chocolate, she will have woken up the craving center in her brain, and want to put inordinate amounts of food into her "mummy tummy".
So she will dine on mashed potatoes, pot roast, and carrots.
Then she will feel like a bloated pig ready for slaughter.
So she will go for a long run, about 7 or 8 miles.
When she comes home, she will feel tired and pretty good about burning all those calories.
So she will reward herself.
With a cookie.
