Master Roshi quotes from Dragon Ball (best)

Master Roshi: A couple billion Zeni...?! Even if I went to a strip club everyday, I wonder just how many years it would take to use it all up...

Master Roshi: Luck is also part of one's skill.

Master Roshi: To think he was capable of the Kikoho... It's a tremendously destructive technique. Many times more so than the Kamehameha. But because it's so powerful, the user can die due to intense energy loss. Even if you don't die, it will still shorten your life span.

Master Roshi: I can't spend my time watching dirty videos with someone like you around!

Turtle Hermit: Shall I take a look at her?
Son Gohan: Can you help her, Turtle Hermit?
Turtle Hermit: I'll give her CPR!

Master Roshi: Goku, Krillin. You two are the ones who taught me that this old man still has a future and it's too early to decide my limits. You're the ones who taught me that by continuing to aim for higher heights.

Master Roshi: That's Goku for you. It would seem the world isn't particularly important in his eyes. Beating opponents who are strong enough to excite him is all he wants.

Piccolo: Five pure-hearted Saiyans? Impossible. Gohan and Goten are the only two like that.
Bulma: How rude of you! Vegeta may be a lost cause, but Trunks certainly has a pure heart!
Piccolo: Someone who has a girlfriend at that age is impure.
Bulma: Whoa! What era do you live in, old man?! Aren't you just being jealous?
Chi-Chi: That's right, Piccolo! Are you saying Goku is impure as well?!
Żółwi Pustelnik: It's true that he's kind, but whether or not a kind idiot who's obsessed with fighting counts as being pure-hearted is debatable.

Bulma: There's no way I'm going by myself, okay? Someone come with me!
Turtle Hermit: Two months round trip, huh? All right, I guess I've got no choice but to go with you.
Bulma: That will just add unnecessary danger!

Master Roshi: Why are you surprised? Cell. Boo. Beerus. Not to mention Goku and Vegeta. You've seen how such amazing people fight closer than anybody else! Attacks from a grunt like that will never hit you if you just stay alert! Have some faith in yourself! Your techniques are from the Turtle School of Martial Arts!
