"Grant me the serenity to accept the things I cannot change, the strength to change the things I can, and the wisdom to know the difference." -- Sounds like a bible quote, but I don't think it is.
"Why sleep now, you'll get enough when you're dead." -- Almost sounds like a coke head trying to keep his homies up.
"If a bitch don't like me there's something wrong with the bitch!" -- Heard it on 50 Cents first album... Power Of The Dollar
