9. David Bowie song on "Extras"
If we're being honest, David Bowie is the funniest thing about this particular Ricky Gervais moment, from his HBO series about an out-of-work actor. The glam rocker cuts right to the heart of Andy Millman's career with an incisive impromptu song that starts "Little fat man who sold his soul" and only gets meaner. But Gervais' facial expressions are priceless.
