During other players' turns try and 'do things' without the others noticing, but obvious enough they see.
Pictured here: Hold something between your nose and upper lip
other examples:
- give yourself a compliment
- put your feet on someone's lap
- wear something from your surroundings as a hat
Make sure the others see but don't be too obvious or you'll get caught...
like a deer in the headlights! During your own turn, you reveal what you 'did' and the group decides if you 'did' the 'something' well enough.
