I have my wife set to Sonic: Green Hill Zone
I have my main phone ring set to the menu theme to Saints Row 3
I have it cutting in right when the music starts to kick off
My moms ring tone is set to that audio clip of Stewie from family guy going Momma, Mommma? Momma!
When ever I miss a call The Price is Right lose music goes off.
When I get a voice mail I have Mass Effect 2's "Assuming Direct Control" sound clip.
When I get a text message the SWtOR Holocall sound clip goes off
When I get a picture message the Star Trek door chime sound clip goes off
For the record the two sound unusually similar. Seriously...

And I have the hamster dance for my alarm clock.
My wife helped me pick out some of them.
