Cameron Diaz may be the tit-ular character in Bad Teacher, but skingy Cameron has no chest apples for her students in this bawdy comedy. Spankfully, Christine Smith, aka Playboy's Miss December 2005, substitutes for a lesson in female anatomy 16 minutes in, when we get a closeup shot of her casaba melons. You'll be feeling pretty handy yourself as Cameron squeezes and pinches Christine's cans, admiring her plastic surgeon's handiwork.

The delicious Ms. Diaz does get goofy-sexy 21 minutes in, where she lures lusty guys into a school car wash posing in teeny-tiny cutoffs and a wet cutoff shirt. We wouldn't mind soaking her with our hose!

Last but not least, we could write an entire essay on Lucy Punch's chest pillows. 45 minutes in, the camera zooms in on Lucy's lungs in a nipply top as she jumps up and down on the dance floor. Bad Teacher will make you reach for your pencil sharpener, and it opens in theaters TODAY!
