Jon Stewart makes his first late night return since the inauguration wearing a dead animal on his head and warns President Trump might go 'full Palpatine'

A stressed seeming Jon Stewart graced late night television by making an appearance on the Late Show. 

When warning about the dangers of Donald Trump's presidency, Stewart invoked the evil Star Wars emperor saying: 'It's going to take...every institutional check and balance this great country can muster to keep [Trump] from going full Palpatine.'

Stewart walked on stage dressed in a comically long tie with a dead rodent wrapped around his head.

The comedian joked with Stephen Colbert that he was under the impression that this is how American men are supposed to dress since President Donald Trump dressed this way for his inauguration.

Stewart said: 'I thought this is how men dressed now. The president sets men’s fashion, and I saw the inauguration. Super long tie, dead animal on head. Boom.' 

Stewart proceeded to say how baffled he was by how Trump has signed 20 executive actions in 10 days. 

He then said Trump would keep going and he happened to have copies of the next three orders. 

Speaking as Trump, Stewart said he was making an executive order: 'By the authority vested in me by the Constitution, I, Donald J. Jonah Jameson Trump, hereby direct that, to secure our border, China shall immediately and without hesitation send us their wall. Done.'

Stewart jokingly said he thought this is how men were supposed to dress now 

The audience roared with laughter then Stewart explained when the wall is delivered America will 'pretend we're not home' so Mexico will have to sign for it. 

He said: 'When the wall arrives at the southern border, we shut the lights; we pretend we’re not home. It’s C.O.D.; Mexico has to sign for it.'

The next executive order was to give America the official language of 'bulls***' not English. 

Stewart joked: 'I, Donald J. Lincoln Kennedy Trump III do pronounce America now finally has an official language.'

'America now finally has an official language. The new official language of the United States is bulls***.'

The final executive order wasn't as much of an order as it was a declaration. Stewart said Trump musty be very tired from signing so many actions.

On a darker note, Stewart delved into the order reciting: 'I, Donald J. Trump, am exhausting. It has been 11 days, Stephen. 11 f****** days. Eleven. The presidency is supposed to age the president, not the public.'

The reason that I, Donald J. Trump, am exhausting is that every instinct and fiber of my pathological self-regard calls me to abusive power. I want — no, deserve — not just your respect but your adoration. 

Parades with the tanks and the synchronized dancing, and why can’t they train 10,000 doves to spell out “Trump” in the clouds? How hard can it be? They’re already flying.

I, Donald J. Trump, am exhausting because it is going to take relentless stamina, vigilance and every institutional check and balance this great country can muster to keep me, Donald J. Trump, from going full Palpatine, with the lightning coming out of the fingertips and “fear leads to anger, anger leads to hate.”

We have never faced this before. Purposeful, vindictive chaos. But perhaps therein lies the saving grace of my, Donald J. Trump’s, presidency.

No one action will be adequate. All actions will be necessary. And if we do not allow Donald Trump to exhaust our fight and somehow come through this presidency calamity-less and constitutionally partially intact, then I, Donald J. Trump, will have demonstrated the greatness of America. Just not the way I thought I was gonna. 

Stewart and Trump have a history of arguing - they famously clashed on Twitter in 2013 after Trump appeared to have a dig about Stewart not using his birth name, tweeting: 'I promise you that I'm much smarter than Jonathan Leibowitz - I mean Jon Stewart. Who, by the way, is totally overrated.'

 Stewart responded by tweeting: 'Many people don’t know this, but Donald Trump’s real name is ‘F***face Von Clownstick.'

Days later Trump wrote in a 1.30am tweet: 'Little Jon Stewart(?) Is a p****, he would be hopeless in a debate with me!'
