Want to feel old? Ferris Bueller came out 30 years ago and Matthew Broderick is now 52. But we won’t address those pesky bits of info. Let’s rather focus on why this movie has remained so popular for all these years, shall we?

For those not familiar with the old favourite Ferris and two mates decide to bunk off school for the day and head out for some adventure. Kinda like how you are staring out of the window right now fantasising about a cold one down by the beach. Doooooo it.

Now the good folk at Huffington Post have compiled a list of nine little known facts about the movie. A few of our favourites below:

Look closely and you’ll discover every license plate in the movie has a meaning. Cameron’s father’s Ferrari had the plate (fittingly) “NRVOUS”… Jeannie’s which read “TBC” for “The Breakfast Club” and Principal Rooney’s which read “4FBDO.”

Charlie Sheen really wasn’t ‘on’ anything during his scene in the film.While the actor has had his share of drug troubles in recent years, sleeplessness, not drugs, were used to help him fit the part of a strung-out, bad boy.

June, 5, 1985 was probably Ferris’ real day off. Experts have pinpointed the actual day Ferris, Cameron, and Sloane painted Chicago red, because of the Braves-Cubs baseball game they attended.

We aren’t suggesting you duck out of the office early, but we could be accused of nudging you somewhere in that direction. Nice day out, isn’t it?
