I'd add Shannon Briggs vs. Sergei Lyahovich to this list as well.

Briggs was throwing just a few punches a round and huffing and puffing then all of a sudden....BAM !

In the post fight interview I remember Jim Gray or someone asking Briggs "What would you have done if you hadn't landed that big punch in the last round ?"

Briggs replied: "I dunno probably gone home and shot myself in the head."

hahaha !
