Dara O Briain - 'Errrrrrrr...'
Jo Brand - 'And um...'
Ross Noble - 'The Errr...'
Eddie Izzard - 'Sooo yeah...'

Hidden Catchphrases
Stephen Fry sticking his finger in his ear.
Or tidying his cards every 5 seconds.
Is that a euphemism?
You're right about Jo Brand, she always does say, "And um ..."
I don't think she qualifies as a comedienne as she doesn't do anything but panel shows. When she turned up on Have I Got Election News for You as the host I just though, "Oh my goodness ... someone put a bullet in me quick."
She's been doing stand up for years! Decades. I think that counts as a comedian.

Does that apply to all the other (male) panellists too?

I really like Jo Brand 
Back on the subject of hidden catchphrases, I think Noel Fielding's overtly casual sip of a drink must apply.*
* I base this purely on his appearances on Buzzcocks.
He (and Julian) do a fake pause just before saying the last word or two of a funny punchline, to make it sound like they've just made it up.
It is very effective!
Johnny Casson, "and umm" at the end of every joke.
Ronnie Corbett "UM"s a lot in Sorry!. Until you notice it, it's not a problem, and then it is.
