Shave, and Shave Alike

You have three teams of 2 people in each team. Team 1 sits on chairs with their arms behind their backs. Team one then have shaving foam put on them by a sensible person. Team 2 then stand in front of team 1 and are blindfolded and are then given a spoon. Team 2 then have to ‘shave’ the person in front of them. The person who does it the quickest wins.
