Banana Peal

The loathsome gods of men have gathered for the first time in the history of the universe, all converging their powers to create the one and single item which is to put to shame anything before it, so powerful that it could shatter worlds and distort the fabric of reality, time and space by simply uttering it's name, while it's strength would've known no boundaries, that was meant to be, until one of the lesser gods, called a simpleton and jester amongst the other lesser gods, has had enough. For too long was this god called a fool and a buffoon by the gods and even his kin, for too long has the god looked into the mirror and felt anger swelling up whenever thinking of his cooler brethren, for too long had he wept his bed and cried in the bathroom alone.
So, to exact his revenge upon those which created him, the lesser god laid in wait as the gods gathered and sought his opportunity. The gods started merging their powers into one and the item of supremacy was being created, the gods were closing in the item as the concentration required reached peaks unseen even by them, but as the last step was to be made, all of them slipped and fell in unison on their backs, underneath theri feet, a banana peal.
