Those 5 Seconds of Summer fellas are currently making their way around the world on their Sounds Live Feels Live tour, and in between ogling at Ashton Irwin's delicious biceps and Calum Hood's glorious lid, we've been doing some research.
And by 'research', we mean watching back all the 5SOS music videos on YouTube surrounded by snacks not feeling a single bit guilty about a second of it. This should totally be a degree, right?
What, mum? What do you mean, 'NO'? If we're not gonna graduate with it, we may as well put all this good 5 Seconds of Summer music video knowledge into a quiz, then - namely this 'Which extra would you be?'
Give it a go and then giz us a tweet over at the usual place to let us know who you get. TAAH BABES. *Prays for the girl in between Ashton and Michael in the car in 'Amnesia'.*
