Early versions of the character first appeared in Parker and Stone's two pre- South Park shorts, " The Spirit of Christmas " (1992 and 1995). In the first Spirit of Christmas short, the character resembling Kenny is unnamed, while the character resembling Cartman is named Kenny. The unnamed Kenny-like character also speaks unmuffled in the first short. Both of these characters get killed in the short. In the second Spirit of Christmas , a character with both Kenny's appearance and name appears and dies. Kenny's first South Park appearance within the series was alongside Kyle , Cartman and Stan in " Cartman Gets an Anal Probe ".
As Jesus vs. Santa became more popular, Parker and Stone began talks of developing the short into a television series. Fox refused to pick up the series, not wanting to air a show that included the character Mr. Hankey , a talking piece of feces.  The two then entered negotiations with both MTV and Comedy Central. Parker preferred the show be produced by Comedy Central, fearing that MTV would turn it into a kids show.  When Comedy Central executive Doug Herzog watched the short, he commissioned for it to be developed into a series.  
Park is well known for her strict, no-compromise adherence to political promises. In 2010, for example, she successfully stopped the Lee administration's attempt to cancel the plan to establish Sejong City , a new national center of administration, arguing the plan was a promise made to people. This conflict between Park and Lee Administration cost her a considerable decrease in her approval rating at the time.  In 2012, Park also vowed to construct a new airport in the southeastern region, a 2008 presidential campaign promise made by GNP but cancelled in 2011, despite claims of economic infeasibility of the plan.
