<p>I remember watching the episode featuring the World Martial Arts tournament. In this particular episode Krillin was against Jackie Chan (Master Roshi). At a time Krillin kicks off Roshi out of the ring, but he flies back using Kamehameha and Krillin still shocked mutters that according of his knowledge only Goku and Master Roshi know this technique. </p>

<p>But I don't recall any incident in which he saw them performing this technique (or even mentioning). </p>

<p>Is there something I missing?</p>

It's the time where we all first seen the Kamehameha performed by Master Roshi. Still don't remember it? Ox-king asked Master Roshi to put out the fire in his castle, Roshi was intended to use Kamehameha to put out the fire but he destroyed the entire castle instead.
