I play sci-fi most of the time. I once had the idea of poisoning some boarding space pirates by mixing bleach and acid, creating chlorine gas. The group loved it and asked for more. So now my search history contains some really questionable stuff.

I actually did this a couple months ago because my DM gave me a flare gun and eventually the question came up: "Hey, where do you keep getting ammunition for this thing?", and so I started a pot ash farm out of the trunk of our troupe's car that I sneak everyone's poop into.
