People who try to put 23 things into Room 101 (plain greedy if you ask me - especially when they waste half of them trying to defend B** B******) :O)
Also:-
Liver
Bagpipes
Boy bands
...and most of all:
Astrology - helloooooo people, it's what we in the real world call "twaddle". "You will receive welcome news from an unexpected visitor today" - yeah, me and about one-twelfth of the world's population, who by amazing coincidence all happen to have birthdays within a month of each other. Oh, come ON!
