Lets also assume they know the mechanics for the VoG and Crota's End.

Didn't yatsharobie (don't know how to spell his name) "the fat one with the sword" saved goku and the rest by cutting vegetta's tail off. At the beginning of dragonball Z. Story would have ended right ther if he wasn't there. Hahaha
