I think they can do wonders with boobs (sometimes) and noses, but beyond that it just doesn't work (chins, lips, butts, lipo).
I should amend it to:
"In porn, for every one great boob job, there are 76 shit ones around the corner."
I think I've seen fewer than 10 boob jobs that I'd describe as truly good. And by that, I mean boob jokes where you have to ask if they've been done or not.
The ammended version is dead-on, Conky. There are good ones, but few and far between.
