So we recently had a rather odd experience with a thread with a supposed lateral thinking exercise that was abandoned by the OP and proved rather frustrating. To remedy this, I present a real lateral thinking exercise, which I will stay around and provide an answer to:
'A man is walking along a corridor with a piece of paper in his hand with information on it. As he is walking the lights in the corridor flicker and he returns back the way he has come. Why?'
You may ask me any questions about any aspect of this tale, but I may only answer with a yes or no answer. I will periodically post summations of the information we have determined so far.
A note: I understand that this is probably quite a well known test, so if you already know the answer please don't spoil it for everyone else, and try and resist the temptation to google it as well. Once we've answered this one I will post a new lateral thinking exercise until people get bored.
