Quotations

The 2000 film Boiler Room makes reference to "pikers" in the following excerpt:

So now you know what's possible, let me tell you what's required. You are required to work your fucking ass off at this firm. We want winners here, not pikers. A piker walks at the bell. A piker asks how much vacation time you get in the first year. Vacation time? People come to work at this firm for one reason: to become filthy rich; that's it. We're not here to make friends; we're not saving the fucking manatees here, guys. You want vacation time, go teach third grade at a public school. (wav, mp3)
