The Dark camera is back up for this interested in seeing an unshaven, hungover student attempt to do work. Why you'd wish to do such a thing is not within my range of understanding but the internet is full of weird people.
Like me.

Edit: The Green Lantern had a ring that worked on his imagination. Anything he imagined came into existence. Was pretty much all powerful (except against yellow... and wood... but then that stopped...)
I think a giant fist would be the most unimaginative weapon in the existence of everything.

Although I'd probobly just use the Ring for obscene gestures and remarkably rude jokes...
