IIRC it was
" *cracks knuckles*.... It's time to kick ass and chew bubble gum.... and I'm all outta gum"
I played the first level quite a few times because it was the most fun, so saw that scene quite a few times.
It's frickin genius. So funny how such a lot of humour sprang out from this. Sometime these 'internet memes' are pretty damned funny.
