Why is Alan Davies always on QI?

[Katymac]

DD would like to know

& she says Stephen Fry has a 'very lovely voice'

More to the point why is QI always on?

I heard that the intension was that SF would be the wise team captain and AB the dim one. But the intended host backed out at the last minute, so SF took the reins.

probably has a contract

i love alan davies!

he's there to make the average qi viewer feel they aren't too daft...

Blue whale

because he's just hilarious

and I'm in love with Mr Fry

Because they knew I'd be watching.
