Settling the scores
Lucas is an instantly recognisable face on little glowing boxes across the country, chiefly on account of his beaming moonface, screen-filling grin and famously lugubrious voice. He shot to fame in 1995 as George Dawes - and indeed as George's sister Marjorie - in Vic Reeves and Bob Mortimer's assuredly daft gameshow Shooting Stars, and hasn't stopped shooting since.

A little bit Welsh
As for Walliams, he's graduated from hanging out with Simon Pegg and writing scripts for Ant and Dec (maybe keep schtumm about that second one, eh?) to a slightly preoccupied starring role in BBC drama Attachments and various cameos including Vulva in Spaced. But it's right here on Rock Profiles that Walliams comes into his own, despite of his role as straight-man in the face of Lucas's lunacy. Walliams's portrayal of Patsy Kensit is a particular treat.

Having a Bowery ball
While Lucas and Walliams have worked together forever (in TV terms at least), they're probably the only double act to have played basically the same role in different productions. Walliams's aforementioned Vulva character, a monstrously pretentious, grotesque, turquoise-painted performance artist, is largely based on legendary New Romantic-era prankster Leigh Bowery; and Lucas recently garnered plaudits aplenty for his over-the-top performance as Bowery in Boy George's 80s-themed stage musical Taboo.

Theakston's peculiar
Of course, Lucas and Walliams's expert pop star hatchet jobs wouldn't have nearly such an impact, were it not for the unfeasibly tall, ever-friendly presence of interviewer Jamie Theakston. It's his job to feed the duo all the best lines and vaguely steer each show to something resembling a conclusion. (That he rarely succeeds is barely relevant.) The show's two series see Theako come up against the likes of Michael Jackson, Simon and Garfunkel, Prince, Blur and Elton John. Somehow he manages to maintain a thin veneer of professionalism throughout.
