What it costs: Potentially into the hundreds of thousands, if not more.
How reality differs from Hollywood: Most car chases that make the news have to do with the police chasing someone, and it usually ends in an arrest. If you ever were, however, to find yourself in an actual car chase in which the world's fate hangs in the balance unless you catch the vehicle in question, one suspects everything would work itself out.
If that turns out not to be the case, and you could have called the authorities and let them handle it, expect to be incarcerated and plan on spending money for bail and a good lawyer. Also expect possible lawsuits from the drivers you banged up – or the owner who lost his fruit stand while you were giving chase.
But you probably don't need to worry much about your insurance, provided you are covered, according to one insurance agent who wished to keep her name out of it, lest she come off as advocating being in a car chase.
"If you're covered, you probably are covered," she says. "Insurance can't stop you from being stupid."
The scene: Inviting two women out on a date – on the same night. (In the movies and TV, it's almost always a guy who is stupid enough to try this.)
Examples where we've seen this: Numerous sitcoms have used this plot device, including "Three's Company," "Family Ties" and more recently, "Community."
What it costs: Expect to double the cost of one date. Also, bring at least $100 or so for incidentals (more on that in a moment).
How reality differs from Hollywood: You know how it is. You've agreed to take your significant other to the movies on the anniversary of your first date, which is the same night your demanding boss has asked you to entertain his single niece, and for complicated reasons, you have to make both parties happy. This sort of thing happens all the time.
Well, maybe not.
Candy Tolentino, founder of the online relationship site MarryMeAlready.com, doesn't recommend that anyone go on two dates at once: "I am all for thinking outside the box when it comes to landing 'the one.' However, I do think trying to secretly go on two dates at once is a recipe for disaster."
But if you were to find yourself in such a predicament, she suggests bringing extra money along for the following:
• Service people. You may need to tip the waitstaff or movie usher so you don't blow your cover.
• Gifts. "In case you find are found out," Tolentino says. "At least a dozen roses might diffuse the situation."
• Cab fare. If you are caught, someone – one of your dates, both of them, you – will need it.
• Airfare. In case you want to continue your sitcom life to its natural conclusion, Tolentino suggests that "due to the unpredictable nature of this endeavor, you'd be wise to purchase an open-ended ticket out of the country beforehand. Tempers will likely flare."
