Once my friends and I decided to play a funny game. I invited the equal number of guys and girls and asked them to stand in a row a guy after a girl.

Then I gave the leader of the row a playing card and told him to take a deep breath as if he's trying to inhale the card. The card stuck to his lips. Then he was told to turn to the next person and the latter had to inhale the card the same way to make it stick to his own lips.

If somebody drops the card, he would kneel and inhale the card without using hands. 2 girls and 3 guys let the card drop down. It looked very funny the view of them crawling on the floor and loudly breathing.

After the last girl in the row managed to receive the card, everybody went to have a break and think of other games.
And what games do you play with your friends?
