The programme's back, with a new format of three guests fighting for the right to put their pet hates in.
Leaving aside the fact that the original Room 101 contained your greatest fears, not just things you don't like, what would you put in?
My current list includes:
Those pathetic 'serving suggestion' pictures on packets of food: I know it's a good idea to serve ice cream in a bowl, and to eat it with a spoon, and no, I didn't expect to find a bowl and spoon in there.
People who get out of cabs and talk very loudly, regardless of the time of night and how many people might be trying to sleep within yards of them.
Tescos.
