Howard K's Lawyer is a Knockout

Let's get ready to ruuummbbllle!!

If you thought Howard K. Stern's attorney was scrappy in the courtroom, wait'll you see what Ron Rale can do in the ring!

TMZ has obtained exclusive footage of a smiling Howard K. at a Muay Thai kickboxing tournament in Southern California back in 1998. Stern is ringside, supporting his longtime friend/lawyer/homeboy. It was Rale's first fight ever -- in the ring, that is. As his future wife Andrea smiles, knowing that Ron could be beaten to a pulp, Rale, a partner at a prestigious L.A. law firm, proceeds to lay the smackdown on some poor dude, sending him to La La Land in less than 10 seconds.

But wait, there's more! Rale's taste for battle brought him back to the ring, this time with 10-time World Kickboxing champ Hector Pena in his corner. Rale opened another can of whoopass on opponent #2, scoring another first round knockout and a cool trophy!
