I must say Bill O' Fuckey and Westboro Baptist would be very high on my list.  Probably both top 5.
Osama Bin Laden, George Bush I guess but he was just a figurehead anyway.  Shia Lebeuofufuooeueuf too, fuck that guy.  And whoever invented multi-funtion touch pads for laptops, and Bill Gates.  And the cops.  All of them.
