In one of the best decisions we've made in life to date, we've put all that Zac Efron oggling to good use and devised a quiz based around matching his topless torso to the movie it appeared in.
(This, ladies and gents, is the reason we went to university. The reason we got degrees. The reason we're #seriousjournos.)
So go on, see if you can match the topless Zac Efron to the film and then give us a tweet over @Sugarscape to let us know how well you did - assuming you can still breathe and have functioning internal organs by then, that is.
