In a TV interview with the makers of the Simpsons, I distinctly remember someone (Mr Groening?) saying they wanted an expression for Homer to use, like Oliver Hardy used in the Laurel and Hardy films. Hardy said "Doooooooooh", but that used too much valuable celluloid time, so it was shortened to "Doh".
Can anyone here support or counter-claim the 'true' origin of 'Doh' ?
