Step 4: Guess that song!
For this all you have to do is make up several small pieces of paper, and write down popular songs on them. The more the better.
Now, stack them into a deck, and have the first player pick one. They don't show anyone. Now, they have a mile (can make it longer or shorter according to age of players) to hum or whistle the song until someone gets it!
Then, just tear the paper in half, the person that guessed right gets one half and the person that gave the clue gets the other half. If no one gets it, then the paper gets crumbled and thrown away. Continue going in a circle so that everyone has the same amount of turns to hum/whistle the tune. The person with the most halves wins!
(It's a lot harder than it seems!)
