Dirty...
Good to see Grapes of Wrath is the highest-rated episode.
Another great cameo from the underrated Kevin Eldon: "Dirty!"
Also see: laughing racist in an Alan Partridge episode; "the actor Kevin Eldon" and 'king of hobbies' Simon Quinlank in Lee & Herring's various comedy shows; Jam; Big Train; and appearances in other stuff by Armando Iannucci, Chris Morris, etc, etc.
