The adage I hate the most is "it is what it is." To me, it's something someone says when they have given up on making it better. I think to discredit it forever, someone should just say "it's what it's" just to show how ridiculous it is. I think I just realized you can't use the contraction "it's" every time it could be used for it is. Because that wouldn't have made any sense either; 'just to show how ridiculous it's"?
