When I first saw this picture of a folded $5 bill showing LOLzy modifications of Abe Lincoln, I thought it was a fake.
But of course I had to try it myself, and, sure enough, it worked. You just make one crease right down the middle of the bill, bisecting Abe’s nose, and then two creases in the opposite direction through Abe’s eyes. Then, viewing it from different angles, you get the effect.
The bill, flat as usual:
Now you too can be the life of the party!
