Do you like to doodle? Do you bore easily? If so, I've got the perfect activity* for you to try.
First you take a piece of paper (or in this case, a bar napkin), fold it in half, and draw something on the bottom half of it. Be careful not to let anyone else see what you're drawing.
Once you're finished with your half of the picture, keep it folded but mark the locations where parts of your drawing end so the person who draws the top half will know where to begin.
Then, hand the paper/napkin to one of your friends, and have them complete the picture without knowing what you drew on the bottom.
Here are the results from when I recently played this game with some of my friends:
Hard Luck Alien Duck
Charlie Brown Cheerleader Chick
Alien EggShell Halibut Man
Fortune Telling Mer-Bird
I don't even know what this is
*It's the perfect thing to do whether you're chilling out with friends at the bar, sitting with your family in church, or trying to avoid falling asleep in class.
