I commonly get called Tim on the phone. Why Tim I have no bloody clue. It's not like my name is even remotely similar. Steve and Tim are very different. If it's not Tim, it's Dave... Dave at least shares a syllabal with my name though how you get from ST to D on pronunciation is beyond me.

Other than that the mispronunciation of my surname is rife and I can't even begin to go in to it. You would never think saying "Cause" (as in "rebel without a cause") with an r on the end of it would be so hard to process for people but it is.
