Foot soldiers, walkies
This warm-up will get us feeling silly and get the blood moving. Everyone start milling around.
All the players are milling around and someone suggests a body part to lead with. Everyone move around as if your left foot was leading your body everywhere. Continue on with various body parts like: knee, bum, right ear. End the exercise when players start calling out internal organs.
Lead with your spleen, or your Id.
Have the players greet each other while interacting. Have people choose their own body part to lead with.
