In this episode of Dragon Ball Z...
Freeza kicks Goku in the face.
Goku recalls that Freeza can't sense ki, so exploits it.
He unleashes a double-barreled Kamehameha,
... then sends it up at Freeza as a distraction.
Freeza is actually not hurt at all.
Which gives Goku a massive erection.
Being kicked into rocks, however, gave Freeza an idea.
He attacks Goku with rocks.
("I'm a freaking genius.")
His rock scheme not working, Freeza tries a full-sized mountain.
Equally unsatisfying results.
But it was merely a ruse to trap Goku!
Then play some volley ball with him.
(Hey, Freeza, quick ripping of Tenshinhan's game...)
... and finally send him to explode.
But Goku's a-okay!
And Freeza thinks it's time to end their warm up.
The space tyrant admits to never having fought such an opponent, apart from his own father.
Meanwhile, on Earth...
Chichi's planned expedition to save Gohan from Freeza goes awry because she wrecked a spaceship several
fillers episodes ago.
Only Dr. Brief repaired it.
so she's going to Namek.
