There are viewer insults AFTER the credits in Bottom: Mindless Violence
I don't know how many people will have discovered this, I only found out coz I was ill in bed and couldn't be bothered to get up and turn the DVD off, but when you get to the end of Bottom: Mindless Violence and it says 'That's it' on the screen, leave it running and it's hillarious.
You can not fast forward, but leave it running and after a while it changes to 'no, really, that's it' and keep it running after that and it gets progressively vulgar, calling you a wanker if you don't turn the DVD off, telling you to F off, calling you a stupid twat, ect.
It goes on like that for about 20 or so insults, but you have to wait about 25 minutes inbetween each one.
Check it out if you have the DVD, it was hillarious to watch.
