‘Doctor Who’ thing of the day: quiz show gets ‘DW’ answer wrong, but no one knows the actual answer

But as the Mirror points out:

A Channel 4 Million Pound Drop answer was ruled incorrect but the question on the longest-serving Doctor Who has even left sci-fi experts baffled.

...

Antony Wainer of the A Doctor Who Appreciation Society, said: "There are different ways to interpret it."

And as io9 explains:

McCoy played the role from 1987 to 1989, and then reprised the role in 1996 — making him technically the longest-serving Doctor. McGann, meanwhile, was the Doctor from 1996 to 2005, if you count all the audio plays he recorded during the time the show was off the air. (And the question says nothing about playing the Doctor on television, just playing the Doctor.) Tennant, meanwhile, only played the Doctor from 2005 to early 2010.

It turns out to be a downright philosophical question at the heart of the conundrum: What constitutes “playing the Doctor”? After all, Jon Pertwee appeared in “The Five Doctors” in 1983, 13 years after he was first cast as the Doctor: does that make him the longest-running Doctor? What about when Peter Davison appeared in “Time Crash” in 2007, 26 years after he began playing the Doctor?

It’s all surprisingly timey-whimey...
