What's your ringtone or notification sound?

My ringtone: 
  

  (oh, sweet memories...)

Scumbag Blues - Them Crooked Vultures or The End Is Begun - Three, both work well as a ringtone

Vibrate.

Ringtone
  

Metal Gear Solid "gunshot" menu sound
 
I have scared the crap out of people with it. Including at least one world-renowned journalist.

My ringtone is Agnus Dei from Mozart's Requiem. 
And my message tone is the really old monophonic Nokia tone. 
 
My phone is always on silent though. 

"Turret Wife Serenade" from the Portal 2 soundtrack.

Regulators . . . MOUNT UP! 
 
For texts I have the Halo dude going "Double Kill!" and on BBM it's "Triple KIll!" haha

 
i hate text notification sounds so thats just vibration or nothing, and ringtone is Last Day of Magic by the Kills, had that for years now

My ringtone is the ComPowder noise from Totally Spies, it used to be my own voice doing a bad impression of a friend for, like, 2 years. 
 
Back when Text Messaging was actually part of my plan, it was just Engineer saying "Spah sappin' mah sentry!"

Mine's the Auburn fight song. 

My phone's been on vibration mode almost from day one, so no ringtones for me.

Currently using the Xbox 360 achievement sound for message notifications.

Lagwagons awesome song Automatic.

Ringtone: MGS Codec

Notification: MGS Alert

The "Heyooo" from those borderlands claptrap episodes.

My ringtone is a combination of Brian Crain - State of the Heart & Two Steps From Hell - Invincible. It's pretty awesome.

As for the text messages i have The Monkey Island - Theme.

I just got a new phone recently and haven't set a text notification sound other than the default, but when I get a call, it's this song, right here:

I've had the MGS codec sound as my ringtone for years. It's kind of perfect, because only a few people actually know what it's from, and to everybody else it just sounds like the typical cell phone chirp. The only problem is that I'm constantly checking my phone any time I play a Metal Gear game.

I wish apple would let me make my own text message tone with jailbreaking my phone.

my phone ring is the default phone ring.
text message alert is the default text message alert.
 
ive never cared enough to change it.

Never owned a cellphone, so nothing.

I'm using a Korean song as a ringtone for my phone.
