This is an old classroom game that can be adapted to play in the car on long trips. It is best played with a family of five.
Number of players:
Choose one person to be In. That person has to cover his eyes.
Secretly pick someone to say the words, “Cheese please,” in a way that will disguise their voice.
The player who is In has to guess who just said, “Cheese please.”
If he gets it right, the person who said, “Cheese please” is in. If the player gets it wrong, another person has a turn.
There’s no real winner, it’s just a funny game where everyone can use silly voices. Keep playing until everyone has had a turn and then go around again.
