The rules are pretty simple, have every one stand in a circle facing the back of the person in front of them. Starting with a random person they will gently prod the person in front of them on the back with either the parsnip or their finger. The person in front of them will then have to guess what it was. If they guess correctly, the prodder is eliminated, if they guess incorrectly then they are eliminated. The next person then takes the parsnip and play keeps proceeding around the circle until there is only one person left.

Scoring is, as always, completely arbitrary, you can award only the winner, score points for correct guesses, or award points on a sliding scale based on when they were eliminated. Decide how you wish based on the number of players.

Obviously it doesn't have to be a parsnip, it could be literally anything. But use a parsnip.

You don't have to play with eliminations, you can just award points for successful guesses.
