The Waltz of Pi

A pie for a pie a tooth for a tooth.
The campus was brightly lit with the suns shining rays and the grass was fresh and bright green. Don walked briskly to class a little bounce in his step due to the crisp weather. His first class was algebra. He sat next to Blake in algebra.
Blake was a very conniving individual indeed. He had quote the reputation on campus as "Sure-Hand, Sure-Hand." He was the pie thrower of campus. If you had angst on someone and needed them ridiculed on campus, call Sure-hand and he'd get the job done.
That day in algebra they were learning those wretched algorithms.
Class crawled on and on it seemed. The desk got closer and closer to many students heads. The monotony was unbearable, then finally, to the happy elation of many, that jubilant sound of freedom, the bell, rang.
The students piled out of the classroom in hordes. Don liked being one of the last ones out. He would carefully stack his folders in his bag and arrange them just so.
"Hey, Brownie, ya got plans tonight?" Blake asked.
"No none tonight-- just algorithms, how bout' you?"
"Aah, cool, so I need your help with a little operation I have."
"The, sure, what is it?"
"Tonight, I'm gonna pie professor Turpin. I just need you to stand in front of a hallway for me and distract him so I can pie him head on."
"Oh, I don't know, Blake."
"All you have to do is stand in the hallway and talk to Turpin."
"Ok, what time?"
"4:13"
So, this parody plays out and the "pie thrower" plays his cards. Mistakenly, throwing a pie from a sideways direction into the professor.
Now, everyone should know that, when pie-ing someone, YOU DO NOT COME FROM A SIDEWAYS ANGLE.
The pie thrower missed missed his aim and was caught and held accountable.
Moral of the story: Pie from the front not from a sideways angle.
The campus newspaper the following week read,
"A pie for a pie a tooth for a tooth."
