This fella was used in a student's assignment in the course I TA for. The students each had to devise a system and create art based on the results of the system. This student decided to collaborate with a large group, and sent requests for self-portraits to about 100 people around the country. Obviously this was my contribution.
When it appeared in the student's presentation, one of the other students shouted out, "What's your deal with bats?!!"
