Fart scene

Hey guys !

I bought the french dvd of this amazing movie yesterday and I have to say, I don't have any regrets, this movie was just hilarious !!

But I was really perplexed by a scene, just past the hour, after we see the red troll assassin, we can clearly hear someone farting and I didn't see you guys talk about it on the thread, so I was wondering :

- Is the fart also in the english copy ?
- If it is, is it made on purpose or is it a goof ?
- If it's not in the english copy, then it's certainly the french "dubbers" (can we say that word ? My english is poor) and that would make it even more epic !

I copied that scene and uploaded it on youtube, so can check on it !
It's at 0.20 sec !
