I don't really make an effort to watch many these days, but some I like are:
Ellen
Graham Norton
Chelsea Handler
Not exactly a talk show, but Joan Rivers on Fashion Police is **** ing brilliant!
Ones I don't like:
Tyra **** ing Banks - makes every show about herself. Every. Single. Show.
Alan Carr - Wastes 10 minutes with every guest on "Ooohhh, shall we have a drink? Go on, let's have a drink; what do you want?" while the audience whoop like rabid hyenas.
Jonathan Ross - Self-indulgent c**t-nugget.
