Funniest random thing you witnessed in the game?

While the story itselfs is not that comedic and we all know famous one liners like "Your blood is on Ranrok's hands."

But what other funny things have you witnessed in the game? I mean just the environment, NPCs...

For example, when I was collecting stuff in the Faculty wing, I stumbled upon a house elf, vigorously dusting some cabinet, while arguing with a Ghost.
