I still like the good old "IT BURNT HOLES IN OUR CUSOMERS HEADS!" sentence from MO...

Furthermore, if you repeatedly click on a unit in StarCrafT, they come up with things like: 'What do I look like? An Orc?' or 'This is not WarCrafT in Space!'

lots of lines from famous movies are used too:

'I love the smell of napalm in the morning!' (Apocalypse Now)
'Do you have questions about propane? or... propane accesories(sp?)' (King of the Hill)
