Entourage, Season 6

[Turtle comes to Ari, seeking help for a business idea, but Ari gives him a hard lesson in business administration with a little help from Lloyd]

Ari:
What do you need, office space, insurance, how many employees? What do you project to earn, what do you need to break even, at what point can your investors see some profit?!

Turtle:
I don't know!

Ari:
[ushers Turtle to seat] Look. When my son was born, my greatest fear was having this conversation. I knew that I would give him anything he wanted 'cause he was my son. I couldn't say No, which sucks, because it wouldn't help him and he'd just end up on the street doing heroin with the two Coreys, because I was too much of a pussy to teach him a lesson. I won't make that mistake with you. Just say No.

Turtle:
I could pull this off, Ari.

Ari:
Come back to me when you could prove it.
