Probably the funnest game you will ever play:

It involves a group of people, and a number of small circles of thick rope.
everyone moves into a circle formation, connected by holding the rope rings in each hand. One or more upside down basic plastic trash cans are placed in the center of the circle (number depending on the number of people).
On go, the goal is to try and pull and or push people into the trash cans, often violently. If you touch the trash can in any way, or let go of your rope you are out. Yanking is often banned. Play continues and the last one standing is the winner. A team version can be played, with teammates alternating in the circle.

It's a totally fun game of strength and skill, and also probably the best exercise you'll get all week. People will do some crazy moves including all manner of smackdowns into the cans. Blisters are common.
