This one’s an oldie but a goodie, the cult classic viral, Snatch Wars.
Still one of the best and funniest re-sync videos to date, this side splitter has Darth Vader voiced as Brick Top from Guy Ritchie’s excellent black-comedy-crime film from 2000, Snatch.
You don’t need to have seen Snatch to find this funny, (I highly recommend you do see it though, it completely rules) but it will definitely add another level if you have.
I must have seen this ten times, but I still crack up when vader leaves the room at around 4:08, then immediately radios the admiral back to call him a c*nt.
Oh, and that should be some indication for you, this one is definitely NSFW and has many, many naughty words, including gratuitous use of the ‘C’ bomb.
