Things Kakashi would never say:
1) Obito was such a weakling.
2) God, I wish I had peripheral vision...
3) No, I don't have pink eye!
4) Sasuke reminds me of Obito.
5) You suck, go burn in hell.
6) I'm so excited.
7) I feel hyper.
8) I feel so...well...youthful!
9) Ha, take that, Guy! Number 50, me!
10) Hey, Asuma, Kurenai, it takes three to party!
11) Jiraiya, share with me your secrets to the way of women!
12) I miss you, Daddy.
13) Heh heh...moooo...heh heh...dance, cow; dance!
14) Pass the porn *cough* ramen, Naruto!
15) I'm naturally a redhead.
16) Wow, Naruto. I could never copy that cool technique! (Get it, Sharingan? xD)
17) You're right, Sakura. I should sit up straight.
18) Sorry, I'm early.
19) Sakura, you're such a goody-two-shoes lovergirl bitch. You fail at life.
20) Naruto, you're an ADHD OCD ADD phsyco. Leave me alone.
21) Sasuke, you're a bastard who cares about no one but yourself. You're blind to your brother's real nature, and you're a total jerk all around. I love you.

Sorry about the last three. I kinda got carried away...
