Oh please, I don't need more heads filled with useless knowledge around than I've already got back at home. What good is all that information when you don't even have a world to live on to use it. [He's not irritated at all with Gohan about that, not at all. Nope.]

Either way, good luck with that. I'd suggest investing in a strap for your glasses if you plan on fighting with them on. [Another small chuckle. How do you even fight in glasses anyway.]
