That annoys me so much, because my brother shouts it constantly. XD

"The balls are inert." XD

DBZ is good at having memorable quotes.

"Because that's MY ninja way" Naruto
I love it when he says that

voooooi- Squalo from Katekyo Hitman Reborn

not REALLY anime but looks like one :P

"Ya Ha" Eyeshield 21

"Love and Peace" Trigun

"Oro" Rurouni Kenshin

"Apapapapaa" Histories Strongest Disciple Kenichi

The whole "did you see it?" thing from Samurai Deeper Kyo

And pretty much anything that Gintoki says in Gintama and 3Z Ginpachi Sensei

"The will to live is stronger than anything."

"Remember kids, a smart man knows when it's time to... run like a little bitch!" Kanta of Desert Punk

"ii imide"~ Motsu from Negima!? I love how he attaches that on to pretty much everything he says. It's translated as "in a good way". He could say something random like, "I'll kill you..." and then add, "ii imide" to the end of it. lol

Kyouichi Houraiji from Tokyo Majin said something along the lines of
"Sorry, can't hear you...don't have my glasses."
it was quite funny at the time :D
