ALL IN FAVOR OF "SPOILING DINNER" RAISE YOUR HANDS

One of my sisters had eight kids. I know. Insane. But she was a saint and could handle eight. One day they were at Mom's and were hungry. They were wolfing down soda crackers. (That's what we called "saltines" in the dark ages.) Anyway, Mom (their Grandma) said, "Don't eat those crackers, it will spoil your dinner!"

My sister looked at the eight kids and said, "Go ahead. Eat the crackers. We should be so lucky they would spoil your dinner."

Now, my question is: Is there a magic food product--like soda crackers...okay, saltines--that would spoil people's dinner? And if so, why isn't the diet industry marketing it? And why don't I have some of it in my kitchen/purse/desk drawer? And do you think it would be a chocolate repelant?

If anyone knows of such a product, then why haven't you told me about it already?!
