What are some boxing matches where the "weaker" guy beat the physically stronger guy?

Name some fights where a less-physically-strong boxer beat up a physically strong guy with a lot of gorilla upper body strength. Specifically, a boxer -- whose upper body is "sub-par" (according to society's standards) and has small shoulders -- boxing the shit out of a sizable guy who has wide shoulders and more or less looks like a gorilla reincarnated as a human being. In my professional opinion, the purest definition of boxing is a physically inferior boxer using skill to beat up a bigger and stronger man. Basically using skill to overcome physical disadvantages. Mauricio Herrera comes to mind. I really want to see Andre Ward vs Adonis Stevenson. Or Mayweather vs GGG. :hitit: http://grabthepopcorn.com/wp-content/uploads/2015/03/brucevsmike.jpg
