A.K.A The only Max Ladon Buff
Mrs. and Mr. Buff got it on in the backseat of a volkswagon. She got "maxed out" by Mr. Buff so they named the kid Max. SEeing as he was born with a 45 inch penis, the Dr. had it mistaken for the ambilical cord and had it cut off...luckily, only 5 inches was taken from the genitalia. They gave him the middle name of LaDon which is french for LongDong.
