Not exactly ruining my life, but EPIC fail nonetheless
When I first got a mobile phone, I did that thing that everyone used to do, ie: go through all the ring tones and choose the one I liked the best (this is before the days of setting anything as your ring tone).

Then I set the ring volume, and chose the "ascending volume" setting, so that the ringing started quietly and got louder.

In B&Q a couple of days later, and someone a couple of aisles away's phone rang.

"Ooh", thought I "that chap's got the same ringtone as me!"
"Wonder why he's not answering"
"He's coming this way..."
*looks round*
*sees no-one*
"But where is he?!"

Then I realised, and pulled my phone out of my pocket, just in time to see "1 missed call" appear on the screen.

*spangs self*
