Tips: Frequent Gets involve a necessity of action - one Player is teaching the other to do something, they are playing a sport, they are working at a factory building ___.
Gimmicks: The Players will often need to verbally justify their positions, but can also describe what they're about to do, to lead the Volunteers to move their bodies appropriately (or not, depending on the whims of the Volunteers). Players describing/engaging in a repetitive physical action (i.e., jumping jacks) can play with the Volunteer and get a good audience reaction.
Variants: Sometimes known as Moving Bodies. You can have more Players (usually no more than three) or fewer Volunteers, if you want to make the Volunteer(s) work harder.
