don't ask "which road leads to heaven". You will get 2 different answers with no way to know which is correct....
ask "if I were to ask you 'which way to heaven?' what would you say?
A truthful man would tell you the correct way....
A liar would also (unwillingly) tell you the correct way....
explanation... if you ask a liar which way to heaven, he says the way to hell...
but, if you ask which one would he say, he lies and tells you the other one which is the way to heaven...
either way, you know which way to go 
or, I am totally screwy and need to go back to logic class....
