I hate those verification boxes on web forms

You know those boxes that have distorted letters and numbers in them that you have to type in when you submit various web forms? I hate them--at least the bad ones. Some aren't THAT bad. I always feel retarded when I try to read the characters. A good 80% of the time, I screw it up when I first try or else I have to request a different code. The ones that really make me mad are the ones with scraggly lines through the characters I'm supposed to read. I understand their function--kind of--but does it have to be so freakin' hard?

Then again, maybe I'm the only one with this issue. That's very possible.
