15. Labyrinth (1986)

The movie: It might appear on the surface to be about fairies, talking worms, and weird clutter-shouldering crones, but Jim Henson's fantasy... actually, no it really is about all of those things. Jennifer Connelly stars as a young babysitter and David Bowie's at his absolute best as the lycra-clad Jared.

Take a drink when: David Bowie sings a song. Sarah says something obnoxious. A weird new creature turns up.

7. Dazed & Confused (1993)

The movie: The nearest American college culture has to a Withnail & I, Richard Linklater's blissed-out 'last day of school' movie revolves around kegs of beer, spliffs, and random violence dished out against younger kids. It's no wonder the film's become a cult classic and spurned on so many drinking games.

Take a drink when: Someone is paddled. A "sixer" is mentioned. Slater says "fuck" and "wasted" in the same sentence. And if you really want to get bladdered, take a swig whenever anyone onscreen does.
