“Should we order the pizza for I.C. Wiener or Seymour Butts?”

In “For a Good Time, Call …” two enemies become friends when they open a phone-sex line together. It’s an unusual way to pay the rent, but offbeat businesses crop up often in the movies.

Forrest Gump (1994)
This Oscar winner might be a little treacly, but it comes with a valuable business lesson: If your boat can survive a hurricane while everyone else’s gets sunk, you will get rich! Why don’t more fishermen try that?

Loverboy (1989)
Also in the “sex sells” vein, this film stars Patrick Dempsey as a pizza delivery guy. When women order a pie with extra anchovies, they actually mean [redacted dirty joke involving the word “sausage”].

Risky Business (1983)
Tom Cruise (when not dancing around in his underwear) starts a brothel in his parents’ house while they’re away for the weekend. Brings in more money than a paper route.

Baby Boom (1987)
Diane Keaton is a high-powered executive, which in the movies means she hates everyone and has no heart. Then she gets a baby! And that solves everything, especially when she starts a baby-food line that takes the country by storm.

The Social Network (2010)
This one kind of puts all the rest to shame, since it’s based on a true story. And the money-making entity the film focuses on is Facebook. Take that, Fake Movie Small Businesses!
