MEDICAL HUMOR
Boneheads – orthopaedics. Overpriced carpenter - orthopaedic doctor
Dr. Chicken Bones - medical slang for Chiroprators that take a little different approach to treating their clients. Some times they practice without a license and only deal in cash or trade.
Does it hurt when you go to that Dr. Chicken Bones?
Sometimes...but afterwards it does make my back feel better
