Jon Stewart takes over Stephen Colbert's desk and takes down Donald Trump

Fans of Jon Stewart were in for a treat last night.

The former host of The Late Show returned to the airwaves following Donald Trump's speech to the Republican National Convention.

Stephen Colbert invited Stewart onto his show for an analysis of Trump, which evolved into a hilarious takedown of Fox TV host Sean Hannity.

Stewart referred to Hannity as "Lumpy". And it came on the day that Fox media supremo Roger Ailes resigned in the wake of a sexual-harassment suit.
