Brain on a stick

I want a hand sketched and scanned image of a human brain being impaled on a stick. Color is optional. I need to use this as a gravatar, the image has to scale down nicely. I don't want anything other than something that came directly from a sketch book. Project goes to anyone who can suggest the best humor to accompany this idea while providing proof that they can draw without using a mouse. Budget is $30 and will be paid by escrow prior to starting.
