Popular TV comic actor Alexander Armstrong is recovering in hospital today after apparently suffering from exploding head syndrome.
The funny man has been a popular face on TV for several years and recently enjoyed massive success when he teamed up with Ben Miller for The Armstrong & Miller Show, in which they created characters like the street-talking RAF pilots.
Armstrong can also currently be seen with comic Chris Addison in Direct Line insurance commercials and as the host of BBC2's afternoon quiz show, Pointless.
He was taken ill during filming of an episode of the BBC's current affairs quiz show, Have I Got News For You? During the episode, to be shown this evening, he apparently became confused and agitated, trying constantly to explain the rules.
Said a show insider: "Alexander's there every day repeating the rules of Pointless at every stage of the programme - it fills time and lets the morons who watch daytime TV keep up.
"But when it came to HIGNFY he lost it... the rules are, of course, notoriously loose and the scoring impossible to follow. He felt he needed to explain and he couldn't.
"In the end his head just exploded."
Doctors at a big London hospital said Armstrong was comfortable and would be released within days.
