8 XXX : dragonsfuckingcars

Man, five years old and already drawing dicks at a 6th Grade level. Kid's gonna go places.
It took me so long to figure out that this was graffiti. I was starting at the colors and thinking, "What's something weird about those blobs of color."
Either that is one amazingly talented 5-year-old, or the artist was not Billy.
Is the dragon's name "Billy"?
Jesus... I must've been one sheltered son of a gun. At age 5 I would search for fossils and draw birds.
If I had to guess, I might suggest that perhaps the dragon attacking the car was done by a five year old named Billy and the penis into the back of it was added later. Just a guess. Edit: I'm definitely leaning towards this answer. Look at the way the specific letters are drawn in the words "Billy Age 5" and then in the words "Dragons fucking cars." Very obvious differences, specifically in the letters g, a and i. I think it is safe to say the title of the picture and the dragon's penis were added after the fact.
