If you see the Buddha on the road, kill him.
The idea behind the line is that you can't see the Buddha on the road, because the Buddha doesn't roll like that. If you do, it's just someone pretending to be the Buddha and if you rid the world of someone or something appearing to be the Buddha, well... the world is better off.
It sounds terrifying but the same applies to other gods.
If you see god on the road, kill him. (For one, God is not a him.)
Or what about this one?
If you see a Church, burn it down.
(Yes, as a pastor, that one keeps me up at night.)
