Zach Galifianakis told Brad Pitt he looks like ''Hitler's dream'' in the latest installment of his spoof chat show.

The 'Hangover' star sat down with the 'Fury' actor for an episode of his Funny or Die programme Between Two Ferns and their hilarious five-minute exchange saw Brad maintain a straight face while repeatedly insulted by the host.

Introducing him as 'Bradley Pitts', Zach opened the interview by saying: how old were you when you lost your virginity? Zero? I can tell you about when I lost my virginity.''

Brad replied: ''I'd really not like to hear that.''

After then asking the hunky star why he ''doesn't take showers'', Zach then said: ''You play a lot of people that are Nazi haters, which is weird to me - because you look like Hitler's dream.''

Brad said: ''Yes I understand the conundrum of it all.''

The 42-year-old actor then asked his guest - who raises six children with wife Angelina Jolie - about his new movie 'Furry' and when it ''comes out on DVD'', before giving him a gift.

Picking up the colourfully-wrapped present, which was clearly a bong, a device for smoking marijuana, Brad asked what it was, and Zach said it was ''a bassoon''.

The 'Burn After Reading' star replied: ''Oh I thought it was a bowling ball. You know I'm a dad now? I don't bassoon at my house anymore.''

Midway through the interview Brad, 50, began to answer a question in detail for the first time when quizzed about his charity work with the Make It Right foundation, but was promptly cut short when Zach invited comic Louis C.K. onto the set for a brief stand-up set.

The chat then turned to Brad's personal life, with Zach asking: ''Is it hard for you to maintain a sun tan? Because you live in your wife's shadow.''

Brad choked on his gum and spat it onto the table, prompting the host to pick it up and put it in his mouth - but then returned it when his famous guest complained it was his ''last piece''.

The 'Birdman' star made his most daring joke in the interview when he asked if seeing Angelina for the first time was similar to the scene in 'Friends' ''when Ross saw Rachel'', referring to the character played by Brad's first wife Jennifer Aniston.

Brad simply rolled his eyes, then when Zach played the show's theme tune, replied: ''I like that song.''

The interview closed with the question: ''Do you think people focus too much on your looks and don't realise you're just a s***ty actor?''

The 'Moneyball' star spat his gum into Zach's eye and barked, ''Next question'' before the credits rolled.
