EDIT: By the way, I'm not totally convinced that all the points that video brings up are edits. Goku's father being a scientist for example... remember that when they made that episode, the Bardock special hadn't been made yet, and probably Toriyama didn't even have an inkling of an idea that he'd eventually do a story about Goku's dad. So they could say whatever they wanted about him and it would stick.

Except the original speech Vegeta gave in the Japanese version said nothing about Burdock being a scientist (it was really just a huge block of treknobabble about how the Moon Blast is able to transform a Saiyan), and by the time they dubbed that episode, the special had been out for several years.
