Well he almost swore in Deadlocked when he said "And my tail feels like it's shoved right up my…." when he first got that armor XD and also when he's arguing with Qwark over driving a spaceship in R&C3, he goes "Captain my…." gets cut off again.
So it didn't surprise me too much but what surprised me is that 'Crap' got censored in the PAL version but not in the NTSC version. But I still think it's funny XD
He also swar when he was talking to clank. It was after you defeat Slag when he said" You know ,ever since the rocket sled, you've been nothing but a pain in my …."
but I'll admit, I giggle when Ratchet cuss but I laugh when I watch the EU PAL version on the cutscene because of the bleep.
