2451Ive heard this phrase many times now, from many different people, explains Dave in his audio commentary.
After I explain what I do for a living I am told this and its considered to be a joke, and original, only everyone seems to do it.
This is because I work on the signals on London Underground and obviously, you know, when Im not doing my job properly, the signals arent working. But I do make sure I always do it properly.
