10. Alan Moore And The Marvel Douche - League Of Extraordinary Gentlemen

In what fans would likely describe as a "classic Moore move", the writer would include a promotion for a 'Marvel Co. Douche' in the advertisement section of the League of Extraordinary Gentlemen #5.

While for many this would merely appear to be a slightly bizarre but legitimate product placement - as the ad is indeed a real one from the early 1900s - it's impossible to not consider Moore's choice a slight towards Marvel themselves, likely a result of his long-standing feud with them over the company having reprinted some of the work he did for them without his permission.

Concerned about the possible backlash from their rival company, DC would change any references to the word 'Marvel' in the ad to the word 'Amaze' - pulping the entire initial release to try and ensure that the potential controversy never got out.
