The X-Files theme song, beat that. Oh you can't because it's awesome.
I also have the "!" metal gear sloid text message, and that shocks me.
Someone quoted before about turning an I-Phone into a portal turret, with some engineering and some crude workings of my college equipment I did that with the phone of everyone in the college, with a motion sensor on mine to say "Is someone there?" or "AAAAAAAAAAAAAAAAAH!" If I drop it. (turnoffable) but the ringtone is, the "MGS Alert!" for text, and "The rambling of the ball the goes "ohh that thing has numbers on it." and stuff.
They gave me thirty quid a phone, they loved it!
