Censorship edits in music

Apparently these edits ( y'know, where they put a 'boink' sound over the rude word ) have several categories :

Blanking; when the volume is set to zero for all or part of the word.
Bleeping; playing a noise, usually a "beep", over all or part of the word.
Resampling; using a like-sounding portion of vocals and music to override the offending word.
Resinging; removing the word or part of the word and keep the instrumental part of the song
Backmasking; taking the offending word and reversing the audio, sometimes the whole audio is reversed (often to simulate a 'backspin' sound), but more usually only the vocal track is reversed.
Skipping; deleting the word from the song without a time delay.

Does anyone know who the first person was to use these techniques? Or do people have any favourite ones, ones where the edits are better than the originals? My fave is 'Bang Bang' by Capone N Noreaga, where Alchemist puts in an amazing backward synth sound over where they say 'shit' in the chorus, when I heard the real version it disappointed me...any more?

If it's possible, can anyone up their examples? I just searched for the 'clean' edits of the Elephant Man and Shante tracks but can't find em. Lol trust Roxanne. They tried to do a clean version of 'Fuck Tha Police' but then just got rid of it on the censored album version because it rendered the track meaningless. It's less what was censored that I'm interested in, more the creative application of theose sort of edits.

Lol thanks for the suggestions though, I'll search around. My ex's daughter used to think that Eminem was actually saying all the edits when I got her his first album, that the noises were actually rude words.
