have u ever seen and herd kennys real voice i have and if u have then just describe him ok

this video has all your answers

Yes,pleanty of times!!!!

Ok...I think that maybe I can describe...
As far as looks go, the video above says that much: dirty blonde hair and defined features
His voice...like a slightly higher version of kyle's, though not annoyingly so
Maybe that works, but idk *shrug*

Interesting facts: Matt Stone usually does his voice when he has the capucha, campana on, but Mike Judge did his voice in the movie when he took his capucha, campana off. Eric Stough does his voice on the mostrar when he doesn't have his capucha, campana on.

The only episode where he talks with his real voice is "The Jeffersons", I think. There was also a small part in "Lice Capades".

tu hear his voice in the south park bigger longer uncut and in the jefersons
