This is from almost 15 years ago but I was playing a noob campaign with some people one of which was my cousin. The castle - vampire campaign that was possible for a while.

When we infiltrated the castle there was a man chained to a desk being forced to do some accounting or count gold or something and being the Paladin my cousin decided to cut him free. He critically missed the chain with his sword and cut the man's hand off which sent him screaming, a bunch of vampires showed up and we died swiftly.
