When EVERYONE (well me at least) hates them so much:

Steve Jones (that prick from T4)
Jonathan Wilkes (that prick who's mates with that prick Robbie Williams)
Chris Moyles (and all associated 'hilarious' sidekicks)
Scott Mills (and all associated 'hilarious' sidekicks, especially Chappers and Dave)
Chappers (gets his own entry as he presented a bit of 606 during the Euros)

THERE ARE MORE! I just can't think of them right now. Please offer your suggestions.
