most memorable line from a film

YOU'RE ONLY SUPPOSED TO BLOW THE BLOODY DOORS OFF!!

I've been saying this since before I even remembered which film it came from. This phrase is  very common in my house for no particular reason and is used when someone does something wrong, even if it's completely unrelated.

The Italian Job, despite it's age, is an amazing film, that a lot of younger people my age, won't have seen but definitely should... it's a classic, with, evidently, some great and very memorable lines.
