During every campout (usually on Saturday night) we have a campfire ceremony. During these, patrols perform funny skits, tell jokes, and tell stories. These are always a lot of fun and give off a good vibe before everyone goes to sleep. Below I have added some links where you can find some skits and other things to do at campfires.
