Open Happiness 

A song written for a Coke commercial.

Cee-Lo Green of Gnarles Barkely, Janelle Monae, Patrick Stump of Fall Out Boy, Brendon Urie (<3) of Panic at the Disco and Travis McCoy of Gym Class Heroes all perform in it.
One of the best, most uplifting songs ever written ever.

Incidentally, the commercial isn't aired on TV. But youtube'll do the trick.

Person 1 to Person 2: Aye yo, what are you listening to??

Person 2: Open Happiness!

Person 1: Ohh man dat's dank!

Person 3: Canyouwoopmedo?

open contract 

Permission to speak your mind honestly

with the expectation offensive ideas will be tolerated.

Eg. "I wanted to talk in private but she told me to say what you have to say right here, right now!" So to me, that was an open contract, so I told her I was not her baby daddy!
