I thought there were a few missed opportunities for jokes here and there...
- They could have made this a pseudo-Christmas special by having Paragus dressed as Santa when he arrives on Earth and presenting the new planet as Vegeta's Christmas present.
- When Goku asks what kind of a person names a planet after themselves, Trunks could have answered "my grandfather" and that'd lead Goku to wonder why he'd never heard about this "Planet Briefs" before.
- When Broly asks about Goku's power level, Goku could have tried to remember the last time it was officially measured and settled on Vegeta's mistaken reading of 1006.
