Dethklok - Crush My Battle Opponent's Balls

Yeah, that's right. My cell phone is the most brutal phone ever.

Nickelback - Animals
It went off 3 times in my last maths lesson so now i'm thinking of putting it on silent

When I get a text it's the theme from House. And when I get a call it's typically Strength by Abingdon Boys School

all of the lights-kanye west

I have different ringtones for different groups. when family rings me, my phone plays 'The Eagles - Hotel California', but for anyone else, its generally the 'Bargearse' tune.
For those who arent familiar with Bargearse (it's an old aussie tv show), have a look at &feature=fvst but you might want to skip past the first 25seconds.
