Yahoo Mail!
Yahoo mail has got to be the most useless email ever invented. It'll give you a bulk folder which is supposed to sort out the "junk". But then it sends everything to the inbox. There have been times when I've left my mailbox unchecked for at most 36 hours and ended up with almost 300 emails, all of which were junk.
One of these days, Alice, one of these days... pow!!! right to the moon!!
