Time: 10 seconds

Mark Weir fought but three times in the UFC, and won but one of those three bouts, but what a win! Over the virtually unknown Eugene Jackson in London, England at UFC 38, the English fighter stunned his opponent in just ten seconds, knocking him out in front of a very approving crowd.

Weir would struggle later in his career, fighting all over the map up until his mid-40s in 2013, but he'll always be known for this explosive moment in the UFC, back when the organization was struggling to succeed under new ownership, and Dana White still had hair.
