It really does speak volumes about how much of a complete and utter psychopath Donald Trump is when we're talking about George W. Bush like he's a funny, affable guy on a late-night US talk show.

Think about that for a minute. Bush was branded as a dangerous warmonger and there were monthly protests leading up to and during the Iraq War, but now people are joking and laughing with the guy on Jimmy Kimmel.

Swings and roundabouts, people.

In any case, George W. Bush spoke to Kimmel about his time as US President, not watching TV (because he was too busy) when he was US President, Will Ferrell's impressions of him and who he felt did the best impression of him during his time in office.

Take a look.
