"Hey Mom, how much longer do I have to wait before the pesticide in my mouth wears off before I can eat?"
"What are you talking about?"
"You know, the pesticide they put in my mouth to prevent cavities."
"Don't you mean fluoride?"
Moe shrugs and says, "Same thing."
Sure they are. One is HARMLESS in the mouth and the other can cause AGONIZING PAIN or worse DEATH. Yup, they are definitely the same thing.
