Don't get me wrong here, because I LOVE Sokka's humor in any situation. However, I think it would get a little stale if they had a character that acted exactly like Sokka. I think Bolin is pretty funny with little lines like "You know what I'm talkin' bout Paboo. Talkin' bout reaaaal love." Haha, come on. If that one didn't make you at least grin you have no soul. Sokka's sarcasm was great, and Bolin's randomness is awesome. I think they are both hilarious.
