Ferris Bueller's Day Off (1986)

I've been meaning to check out Ferris Bueller's Day Off since I saw the musical scene in Easy A but, for a reason or another — the latest being the idiotic idea to watch Step Brothers — I kept putting it off. 

The film follows a day in the life of Ferris Bueller (Matthew Broderick), a popular high school student who gets away with everything. On this particular day, he fakes sick to take a day off from school and enjoy Chicago with his best friend, Cameron (Alan Ruck), and his girlfriend, Sloane (Mia Sara), while trying to outwit Ed Rooney (Jeffrey Jones), the suspicious school principal who wants to prove Ferris is not sick, and his sister, Jeanie (Jennifer Grey), who is sick of her brother getting away with his tricks all the time.
