Who makes it has no need of it. Who buys it has no use for it. Who uses it has no knowledge of it.
Heared that one before, a coffin.
Okay, you just died and you end up in a place where theres 2 doors, one is heaven and one is hell, but you don't know which is which.
There's 2 men outside, and all you know is that one of them ALWAYS tells the truth, and the other ALWAYS lies.
Both of these men know which door is which, but you don't know which is truthful and which is the liar.
You are only allowed 1 question to ask one of them, what do you ask and which door do you take?
