One slow night at KIRO-TV, the man who directed the 5PM and 11PM Eyewitness News shows asked me if I could make Porky Pig stutter longer. At that time the J.P. Patches show had a large collection of Warner Bros. cartoons. I went to our film library and got one I was sure Porky Pig stutters as he says “That’s All Folks”. The projectionist loaded up the film and I recorded the audio from a 16mm print and proceeded (the hard way, by hand) to edit and loop the stutter. It caused many laughs when I completed it. I did use it on JP’s show from time to time. This was done at least 35 years ago.
