Everyone stands in a circle (alternate boy/girl if possible). Everyone holds hands. There is a bucket or a large trash can in the center (just short enough to jump over if needed). Everyone can try to pull each other so that someone either touches the trash can (which gets them out) or get two people to let go of their grip (both go out).
This worked best with around 10 to 20 people, but can be played with any number. It can be fairly tiring, can be played indoors our out. We played it as part of a combined FHE for singles, but it could be integrated into any activities night or as the FHE activity.
