When BB first started about 10 years ago everyone at my workplace was talking about it. I was the oddity who didn't watch it. Nowadays, no one at all is talking about CBB. It's a silly space-filler.
for one fleeting moment, I thought the OP was talking about ceebeebies.
(sorry)
Haven't seen CBB for years.
Am still having nightmares about George Galloway and Rula Lenska.
