When you gotta go, you gotta go. But when you’re watching a movie, how do you time your bathroom break so you don’t miss anything good?

That’s the question the people behind RunPee.com set out to answer, and answer it they did, with a website (and now an iPhone app) that tells you the best time during a given film to run to the washroom.

The interface looks like this:

It tells you when the perfect pee break happens, what cues to watch for, how long you have to get there and back, and what happened while you were, ahem, powdering your nose. And if you’re using the mobile version, your phone will vibrate (because you would never leave your ringer on in the theatre, right?) a couple of minutes in advance to remind you that your pee break is coming up. Their selection of pee-break-vetted movies is limited right now, but they promise new listings on a regular basis.

So it might be worth looking into if you’re coming to see any of the following movies at the Mayfair this month:

Zombieland (four potential breaks)

Cloudy with a Chance of Meatballs (three potential breaks)

Jennifer’s Body (four potential breaks)

The Informant! (three potential breaks)

Inglourious Basterds (four potential breaks)

It’s true: technology really does make our lives better.

Cut.
