Banned for superfluous banning.

^^Banned and I'll roast you for dinner.
No, I don't want a bobble cap for dinner! Banned for doing the ninja again.

Banned because only those of 8th kyu and above can "do the ninja", so you can't ban the previous person for "doing the ninja", because, technically, he/she had been unable to, anyway.

Banned for knowing too much ninja stuff.

Banned because you waddle on my way again.

Banned because that makes no sense.

Banned for lack of logic. Ducks walk waddling, and Doc's avatar is a duck.

Banned for teaching him something. You should've let him learn it himself.

Banned because mentors speed up the process of learning.

Banned because u still dont know a thing

Banned for having weird gibberish under your name.

Banned because reds should be banned. Look at the mess they flooded us all with!

Banned for political shunning.

Banned for not siding with Warren Beatty and Diane Keaton.

Banned because the weekend is over and I'm in a banning mood.
