Another version I've heard of this is with film censorship - apparently when Hitchcock made Psycho, the film censor (I think in the UK - the BBFC) wouldn't give the film a certificate because it was too extreme for the era - too much nudity, too much violence - and suggested a few cuts to just trim back some of the offending shots.

Hitchock said of course he would, took the film back, and sat on it for a couple of weeks. He later sent back the 'fixed' version, and the censor was much happier with the 'changes' and certified it for release.
