Have the second person whisper it to the third and continue until everyone in the car has had the story or sentence whispered to them. Have the last person repeat the story out loud so that everyone can hear. Hawaii Five-0, Gilligan's Island, Flipper, Brady Bunch, etc. The person who guesses correctly does the next song. Simple and silly.
Questions is truly a classic game.
There are many variations of this game. One person thinks of something that falls under the category of an animal, vegetable or mineral. And after 20 questions are asked, if the players have not already guessed the answer, each player gets a last chance to make a guess. Typically the winner tries to stump the group next.
