Keeping Your Shirt On

My math class this year had a contest early in the first semester where everyone could design a shirt and we’d vote on one to become our class shirt.

Fast forward to second semester finals and I decide to commemorate our last day in class by wearing the winning shirt. My teacher is known to be a bit of a joker, so when he silently walks to my desk and scribbles something on my scantron I assume he’s messing with me and I look up at him, confused.

He just said “you picked the right shirt” and walked away. I looked down and he had scribbled “+1” on my test to give me an extra credit point.
