This is one of my favorite bits of all time. I often wondered whether the original was scripted or done off-the-cuff but you know what? Not actually knowing is part of the magic.
"This is the first time Turbo Encabulator was recorded with picture. I shot this in the late 70's at Regan Studios in Detroit on 16mm film. The narrator and writer is Bud Haggert. He was the top voice-over talent on technical films. He wrote the script because he rarely understood the technical copy he was asked to read and felt he shouldn't be alone. We had just finished a production for GMC Trucks and Bud asked since this was the perfect setting could we film his Turbo Encabulator script. [...] Dave Rondot (me) was the director and John Choate was the DP on this production. The first laugh at the end is mine. My hat's off to Bud a true talent."
hopefully the magic is still somewhat intact ;^)
