You will have to prepare for this one by writing things on cards. One person is going to try to get the rest of their team to guess as many of the things on their cards as they can in a certain time limit. The only thing they are allowed to do to help their team guess what's written on the cards is make noises. No words, no tunes, just noises. Most cards correctly guessed wins.

Scoring is, as always, completely arbitrary, you can award only the winner, score points per potato, or award points on a sliding scale from winner to loser. Decide how you wish based on the number of players.

It's best to have the person making the noises sit with their back to their team so they are not tempted to give clues with their expression, etc.

Make it tricky, but not impossible. Think: Making a coffee, taking an elevator, using the bathroom, vacuuming...
