A corruption of "The Road not Taken" by Robert Frost. A friend of mine did this for his Poetry elective. His turned into an epic battle sequence. I thought it'd be fun, and tried my hand at it. Here's what I came up with.
Two paths diverged in a yellow wood,
and at the fork, two strange men stood.
One was said always to lie,
the other only truth came by.
You have but one question to ask, stranger.
For down one path lies grave danger.
So what question will pass your lips,
so you may avoid the wrong tips?
