One time I went to a play and there was a fog machine involved. I was in the front row. After it had been used, I noticed one of the actors seemed kind of distracted. After a few minutes, I realized that he kept looking at me, so I looked down at my shirt and saw that it was absolutely soaked with blood from the horrifying nosebleed the fog machine had apparently given me. You see, when I get a nosebleed, it's not just a little trickle. It looks like I have been stabbed in the middle of the face. So yeah. I had to try to discreetly sneak out of the theater and into a bathroom looking like I had just cut someone to death and had tried to eat their corpse.
