Rotten molar

A blonde goes to the dentist. The dentist takes a look and says, "Yeah, that tooth is completely rotten, l'm gonna have to pull it. Let me get you some anesthesia." The blonde quickly says, "No way! That tooth's been hurting me for months. Now it's his turn to feel pain!" About an hour later, she's at a sandwich shop, trying to shove a baguette up her butt. The shop owner says, "What on earth are you doing?!" She answers, "The dentist pulled my left molar and told me to eat on the other side for a week!"
