Former Ultimate Fighting Championship (UFC) Welterweight and Lightweight champion BJ Penn has accumulated many memorable moments inside the Octagon during his 16-year run with the promotion, so it’d be pretty hard to rank the top eight.

8. Knocking Matt Hughes at UFC 123 in 21 seconds.
7. Defending lightweight title against Diego Sanchez at UFC 107.
6. Knocking out Caol Uno in 11 seconds at UFC 34.
