If there's no damage to the business end, you could play with it if you have a good stroke and the ability to ignore your eyes crying foul when it moves. You could name it, "The Politician".
If you really feel like trying to straighten it and aren't worried about ruining it:
Mark the high points with a pencil
Heat it the opposite (low) side gently with dry heat (burner or heat gun)
Bend it back slowly against a stable surface (counter / worktable top)
Small corrections are best, don't try to do it all at once
I seriously doubt it could actually be straightened, but it could be a good learning experience. An LD shaft will cost you more than $160 at any rate.
