One time, I slept through a final exam, but woke up and ran yo the class and there was only 10 min left and only one dude still sitting in the back, and the prof said I couldn't take the test, so I made a bet with her that I could finish the whole test in 10 minutes and she accepted the bet... And I finished in 5 minutes and got an A. It was an essay test. Afterwards she emailed me and said "of you're xyz, who emailed me with the thesis about reasons for industrialization" (paraphrasing but "oh you're... " was in there).

Highlight of my time in college. 10/10
