I'll just share this because it made me laugh.
I went to a job yesterday for someone I do quite a bit of work for to take out a door and frame and replace it with new ones. When I got there the door was locked (I could get to both sides of it though) so I rang the boss for the keys. He says to me "Oh yeah, you've got to break into it first!"
Talk about moving the goal posts!
Still, after grinding off the hinges it was quite a nice straight forward job (besides having to plane the frame down to get it to fit in the opening).
