Make a note in your diaries (and cross out the other one)

See me on Blue Peter on Wednesday December 12th! And not the 5th, as I might have said before! It's being recorded in advance, you see.

Check out my memory chimp friends on BBC News! In fact, the performance you can see by clicking on 'number memory test' is rather more impressive than anything I can do (without practice, anyway), although I think Ramón Campayo, who specialises in split-second memorisation of random digits, could still beat them. Actually, I wonder whether that film's a bit misleading and there's a limited number of positional distributions of digits that the chimp has seen plenty of times before, but that's just me being a sceptic. Still, I think tomorrow I get to have a go at the same test, or something more similar to it than the one they knocked together for this documentary last time - we're basically redoing the whole thing that I filmed with them previously.

The life of a memory man really is groovy, isn't it?
