This is what happens when you make a bet with a teacher, kids. Learn your lesson. 

Terry Austen teaches math at St. Patrick's High School in Portland, Michigan. One of his students, an aspiring chef, came into class and said that "geometry is boring." Personally, I can't argue with that. But Mr. Austen disagreed.

He said, "Would it help if I break-danced?" Not only did the student say yes, but she offered to bake him a caramel apple pie if he did it.

I mean, I could make all kinds of pi vs pie jokes here, cuz he's a math teacher. But forget that - he did it. And brought him not one, but TWO pies.
