(“You got a pretty mouth, Nate.”)

During Steve Cofield’s Vegas-based ESPN Radio show today, Donald Cerrone recalled an incident he had recently with Nate Diaz,  and to put it lightly, he isn’t impressed with the level of disrespect his UFC 141 opponent showed him.

According to Cerrone, the confrontation happened at the open workouts for UFC 137 and he had no warning that it was going to go south quickly when he approached his teammate and friend Leonard Garcia who happened to be talking to Nate at the time.

Even though it never made it onto the broadcast of WEC 36 — a gross oversight that actually led to people getting demoted — the lightweight war between "Razor" Rob McCullough and Donald "Cowboy" Cerrone still managed to make it onto many MMA pundits’ fights-of-the-year lists. But unless you caught the WEC’s "Best of 2008" special last month, this may be the first time you’ll see it in its entirety. Part one is above, and part two is after the jump; major props to MMA Scraps.

The tone is set in the first round round as McCullough drops the much-taller Cerrone with punches twice, but Cowboy manages to keep his shit together, score a knockdown of his own, then pounce on Razor and nail him with some heavy ground-and-pound. A bloodied and mouthpiece-less McCullough reverses the position, but finds himself knocked to the mat two more times before the bell rings. And that’s just the first five minutes. Enjoy…
