Used in the movie Wall Street to justify insider trading too:

Bud: Lou, I got a sure thing. Anacott Steel.

Lou: No such thing, except death and taxes. Not a good company any more. No fundamentals. What's goin' on, Bud? You know something? Remember, there are no short cuts, son. Quick-buck artists come and go with every bull market. The steady players make it through the bear markets. You're a part of something here, Bud. The money you make for people creates science and research jobs. Don't sell that out.

Bud: You're right, but you gotta get to the big time first, then you can do good things.

Lou: You can't get a little bit pregnant, son.

Bud: Lou, trust me. lt's a winner. Buy it.
