Once there was three nuns. Now they were so good to God he showed himself to them. "You have been so good to me that I'm going to do you a favor. Jump off that cliff and name any animal and you will turn into that animal." The nuns all shouted with joy.
The first one jumped off and said "Butterfly!" So she turned into one. The second one jumped off and said "Swan!" So she turned into one. The third one was running when she tripped and said "Oh shit!"
