English vs Ebonics

English: This is your Captain speaking, we have leveled off and are cruising at flight level three five zero.   Feel free to move about the cabin.  Also the First Officer has turned off the no smoking sign, the flight attendants will be serving cocktails and refreshments momentarily, so just sit back and enjoy the rest of the flight.  We'll be arriving at our destination in 20 minutes and I expect no delays. Enjoy the rest of your flight.
Ebonics: Ebonia Airlines Dis be yo' main man, we be chillin at tray-five -o, if you be flexin, get up off yo ass and shake that thang, my homey be killin' the man's opression.  If you wanna smoke chronic, just hang loose blood, them bitches be cruizin' on up with some forty-ounce 8-ball, so stop trippin' and sit your ass back down.  We be in the hood in no time afterall, I be bumpin switches all da' way. Peace out!
