I think publical and publically are rare alternatives to public and publicly. They do seem to jar.
I wonder whether it's time for Jeremy Paxman to step aside on University Challenge. When someone interrupts a question he should stop immediately but he always carries on for a bit, giving the interrupter an unfair bonus. It's as though it takes a short while for the buzzer to register with him. Also, last night there was an odd pause when someone answered incorrectly and he had to think what to do next, namely offer the question to the other team.
They're all signs of ageing, perhaps. But on top of that he doesn't always pronounce uncommon words and names properly. He should do his homework before the programme starts.
At least he's better than John Humphrys was on Mastermind. He would always respond to a correct answer with a "yup". Clive Myrie is very good.
