This is the famous Mcdonalds rap that someone pranked Mcdonalds with in a youtube video. Here are the lyrics.

Boom, Boom Boom, Big Mac (all throughout the song along with beatboxing)

I need a double cheese burger and hold the lettuce

Dont be frontin’ son no seeds on the bun

we be up in this drive through order for two

I gots a cravin’ for a number nine like my shoe

We need some chicken up in here, in this skizzle

Forizzle  my mizzle, extra salt on da’ frizzle

Doctor Pepper my brother, another fo’ ya’ mothah’

Double Double Supersize

And don’t forget the fries
