Fights where much smaller fighter beat a bigger fighter?

I can't name fights other than what the other posts just stated but Sadam Ali just beat Cotto

David vs Goliath

[Pocket Dogs!]

Not gonna include Pac v Oscar because Oscar was a dead man walking at that weight.

Disregarding the dead man walking thing, I still remember a tweet from one boxing writer when round 1 was starting that Pacquiao looked like a small boy in the ring compared to Oscar's size.

You see the difference in size it's like a grade one vs grade six student.
