Making The Grade

Years ago, back when I was in college, I was better at hauling kegs than carrying a courseload.
My GPA was horrifying.
However, I was making good cash running parties, so I figured I could buy my way out of the mess I’ve made.
I caught the professor at one of the parties, a Wheel Of Fortune-themed party, and I told him “I know I’m getting an F, but I’d like to buy a vowel, please.”
Five hundred bucks, it cost me.
That night, the professor shacked up with a Freshman and got fired. His TA turned in the F.
