WATCH: Hilarious clips of celebrities reading 50 Shades of Grey

Whoever came up with the Top 10 list of celebrities reading sections of 50 Shades of Grey REALLY knows what makes the internet tick. It's gold-dust. (So thank you, Flavourwire's Emily Temple.)

Will Ferrel and Zach Galifianakis stumble through a duet in prim style, above, backed by seductive jazz saxophone.

Fans of 90s shoot-'em-up Duke Nukem will also be delighted by the rendition of voice actor Jon St. John, whose gravel-throated accent is more often employed to utter threats at invading alien life-forms.

And any 50 Shades performance line-up should give honourable mention to the 50 different accents of impressionist Brock Baker - self-styled "Man of a Kajillion Voices". Mickey Mouse has never sounded quite so, erm, excited.
