Marilyn Manson was planning to release a 'Celebritarian' album. But shit happened and we got Eat Me, Drink Me instead.
Which would have been much better than Eat Me Drink Me, IMO - only album I've hated.
Other Marilyn Manson related PODs -
Trent Reznor decided to re-record and himself produce the debut album Portrait of an American Family after disliking the original producer's softening of their sound.
Interscope, in part because of the below point among others, almost didn't release Portrait. In such a situation Reznor would have invoked a clause allowing him to release anything by him or another artist under his Nothing label through a different label. They got as far as talking to Maverick, Madonna's label, before they worked things out.
Marilyn claims he ran into Axl Rose at a club and told him about Charles Manson's album. IOTL Axl covered "Look At Your Game, Girl" as a hidden track, drawing protests from the families of the survivors. Marilyn said this nearly knocked his own cover/remake, "My Monkey", off the album. If this run-in doesn't happen it could have practically nil effect, but on the other hand maybe the family protests over that - which could have a slight Body Count effect as people check out the album, leading to pre-Sweet Dreams success.
The last one that would probably require an ASB - Jordowsky makes a movie based on Holywood.
Joel Hodgson auditioned for the role of Philo in UHF.
IIRC Al wanted him, but he ended up being busy with MST.
Speaking of which, MST could have been 2K instead of 3K according to one story about it's title.
Joel has also said if Mike was there from the beginning he might have been host due to Joel's discomfort in front of the camera.
A major one for MiSTies - they signed with a less clueless studio to do the movie.
