wrong number

You know what really pisses me off sometimes? Rude arseholes who dial wrong numbers and don't even have the courtesy to apologize.

Observe:
Phone rings. I run frantically from my computer to the phone because no one is patient enough to wait for the phone to ring more than one time anymore. Pick up.
Me: Hello.
Arse: ...
Me: Hello??
Arse: ...
Me: HELLO?!!
Arse: *mumbles an incoherent name*
Me: What???
Arse: *mumbles incoherent name again*
(At which point I'm thinking, dude. I didn't get you the first time. Speak CLEARER.)
Me: Er. Wrong number.
And being the arse that he is, the arse just bloody hangs up on me.

Talk about a WTF moment.
