Yep - another example of the Beeb hitting on a winning format and flogging it to death. Still, I do watch it whenver i get the chance purely to try and get a 0 answer - I'm sure most people who watch it do exactly the same.
The Chase is another one - good concept but on too much
People watch pointless to try and get a pointless answer, my, how people can be strange sometimes!

Did you see that Channel 4 programme about TV in the 70s the other week. "Blacked up Jock" FFS!
