La Finale

Jackie Chun actually fired the wave at the moon, not Goku. Goku is found sleeping in the rubble, so they wake him up to continue the match. Krillin lends Goku his clothes. Once the match resumes, Jackie Chun tries to fire another Kamehameha wave at Goku, but finds that he doesn't have the energy. Goku kicks him out of the ring, but Jackie avoids hitting the ground by sticking his foot inside the wall. With both of them completely exhausted, they on a straightforward finish to the match. After a long bit of fighting, Goku and Jackie jump and kick each other in the face, knocking them both down. The count goes past 10, so the rules say the first person to stand up and declare victory wins. Goku struggles to his feet and nearly finishes his victory declaration, but collapses. Then Jackie Chun gets up and declares victory. After the match, Jackie secretly takes off his disguise, and they all go out to eat. Goku eats so much that Master Roshi has to spend his entire $500,000 prize on the meal.
