Mottos in anime

Which ones do you think are the most rertarded or the best mottos.
I have to go with Shichio Makoto's motto "the strong lives the weak dies" and with the X-LAWS motto that is quite similiar to the Aku Soku Zan.

I think the dumbest one was " Don't believe in youself, believe in me who believes in you "

Such a gay line. Can't even remember what it was from, just how stupid it was.
