Yeah. He learned the Kamehameha from watching Roshi do it that one time. Used as a gag where Roshi talks about the decades-long process of learning it himself, before Goku does it in one try.
The "stolen techniques" gag is basically just Cell being a contrary jerk in response to Goku getting all high-and-mighty about Cell using their moves.
I have a message from another time...The Kaioken and Genki-Dama are the only moves in Goku's repertoire for which he actually received formal training.
Goku is a notorious move-thief. It was more evident in the early parts of the series, and was a key part of where Goku's fighting genius reputation began. Goku would learn new moves by watching adversaries perform them and then doing them himself, and often doing them better. A great example of this is during the 21st Tenkaichi Budokai, during his climactic duel with Kame-sennin.
During this fight, Goku instantly learns the Zanzoken during his fight with Kame-sennin after seeing the latter perform it and starts using it against him. Kame-sennin tries to counter him by doing a double Zanzoken, faking Goku out by creating a second image once the kid's learned to counter the move. Goku, however, takes this as a challenge and counters Kame-sennin by making a triple Zanzoken.
My Tumblr. Currently side-by-side liveblogging Digimon Adventure, sub vs dub.The anime ran headfirst into the brick wall of overtaking the manga. Waiting for new chapters to come out forced them to do a ton of filler arcs. The nature of the series emphasizing long fights against single opponents didn't really make for natural opportunities for this either, which is how we wound up with really forced bits like Goku v. Frieza being interrupted so that the Earthlings on Kaio-sama's planet could duke it out with the Ginyu Force or Captain Ginyu could body-steal Bulma and cause havoc for a bit among the spectator protagonists.
When filler occurred during resting periods such as Gohan's training filler or Goku and Piccolo driving cars during the three-year training period for the Androids, it tended to be of higher quality than the shit they had to throw together to buy time between punches in ongoing fights.
This is also the reason why Dragon Ball wound up with its reputation of "two guys staring at each other and screaming for twenty minutes"; because they had to really stretch to get one or two manga chapters to equal an episode. "Here's a panel of Goku powering up, and another one of him punching Frieza in the face. Make that last three minutes."

A lot of adapted fighting anime do that: lots of manga fights would only take a minute otherwise, so you often get padding that shows the curbstomped party putting up more of a fighting chance.

Gohan's training montage during the Saiyan Arc is great. It's amazing to think that it's not in the manga at all. I always liked that moment of Gohan finding his way back home, but deciding to go back to his training anyway so he can protect the Earth, even as a kid.
That move is so unfair that it's not even funny.

I don't think I ever even saw most of the ultimates
. I just enjoyed using the assist characters and special combos too much.
I wish, when they were saying that combined line at the end, instead of what Vegeta said, he was the one to remember Jesus in the true meaning of Christmas.
Ah well.
On second watch of the first battle scene, I understood why Vegeta wasn't pictured fighting. True to his word, he refused to fight to the song Jingle Bells (not the joke about jingling bells).
Never Found the Body means he may still be alive.

Team Four Star likes to say that Kakarot stole the techniques he often uses but isn't a vital part of stealing the fact that it's done without consent? Kakarot was taught the Kaioken, Kamehameha, and the Spirit Bomb. Even in the abridged series, he never maliciously claims that he created those techniques.
