A particularly silly and amusing group game I like is called slack jawed dance off. Two people face one another, letting their jaws hang slack and open. They must maintain eye contact at all times and keep their jaw slack. Both begin dancing in such a manner as to get the other person to laugh or smile. They must continue dancing the whole time and no talking. When one person cracks up or smiles, they have to step aside and make way for a new challenger.
Obviously, this one is not presently safe, in light of current circumstances. But it will be one day, so wanted to share before I forgot.
