Law & Order, Season 7

Peterson:
Why would I kill my friend over 3% of my net worth?

Curtis:
Leverage, Peterson. It was collateral for part of one loan for the airline, that was part of your transportation holding company, which was financed up to your eyebrows. So, you pull out one brick from that wall, it comes crashing down, you gotta go back to collecting Lincoln pennies.

Peterson:
Rey, Rey, Rey, Rey! Do me a favor: go to business school for a couple of years before you explain my financing to me, OK?

[Van Buren summons Curtis to leave the room]

Curtis:
I can't talk right now - I have to go to business school.
