This one still makes me laugh :-)

   "One night I was being dropped off at home by
    a few mates after quite a heavy night
    drinking. After fumbling around for my keys, I
    realised that my phone wasn't in the pocket
    where I usually keep it. Hoping that I'd left
    it in the car, as opposed to losing it in the
    pub, I quickly rang my friends who were at
    that very minute speeding away.

    The conversation went something like:
      "Hi."
      "Hi, have I left my phone in the car, cos I
       don't have it?"
      "What are you speaking to me on?"
      "S**t," (Furness)

It hasn't happened to me yet (that i remember), though it's probably just a matter of time.
