Here's one that gigi's made me think of:
My mom puts a scripture as part of her answering machine message. So, not only is it like "HERE HAVE SOME RELIGION WITH YOUR PHONE CALL", but it makes the damn message go on FOREVER. Because directly after the scripture, she tells me the number that I have dialed (yes, she says, you have reached (xxx)xxx-xxxx as if I didn't KNOW that I JUST DIALED that number!), instructs me to leave a message (after the beep of course!) and that she will get back to me as soon as possible.
And I'm sitting there tapping my foot like COME ON! I GOT STUFF TO DO! Leaving large messages as your recordings is like "Hey, how can I take up as much of your time as possible?"
