Something humorous or silly that you've done camping

Had a replacement starter battery. When I opened the box, it came with the battery and vials of acid to add to the cells. So, I started doing basic safety precautions, like a hose with running water nearby, safety glasses, clothes and so on. Had some people from a nearby campsite wonder what I was doing, and they couldn't figure out if I was fixing a battery or making meth, until I got the battery acid in the cells, sealed it up, and put it in my generator.
