mutant times report

It is a little reported fact I first gleaned from an old 1968 copy of the Mutant Times, that MutantKung-FuChicken resulted from a cross-contamination of mold spores from the peanuts in Kung-Pao Chicken eaten at a World Championship Kung Fu competition the previous year. As at first those that ate the dish seemed to gain strength (an initial side effect of the - at the time unsuspected - toxins), the other masters with an envious eye unworthy of their stature but not to be outdone, joined in with gusto. Sadly, as the initial effects wore off, it made them all too chicken to fight. They founded their own organisation of MutantKung-FuChickens the following year.

Or, for an alternate theory, see this version of the story.
