Joke Decoder (panel 27)

vert-27Adult Spine Book Store

Chiropractors are constantly trying to stay current with the never-ending information that is generated in the scientific research.  Here we see Vert doing just that, only he’s doing it in an X-Rated Adult Spine Book Store!  His eyes widen in amazement has he stares at a page in 101 X-Ray Positions.  By his side sits The Joy of X-ray.  Note the sign hanging by the door:  “No One Under Risser 5 Permitted.”  [Risser’s sign is a radiographic marker of skeletal maturity — grade 5 being fully mature — see the “Puberty” cartoon for another joke using Risser’s sign].
