The Simpsons has released a teaser of its parody of US President Donald Trump's first 100 days in office ahead of the milestone on 29 April.

A clip of the show shows a disturbing ending for White House press secretary Sean Spicer, as well as taking a dig at the president and members of his family.

The press secretary is featured hanging next to his podium, wearing a notice that reads 'I quit', while in a nearby room controversial former Breitbart executive turned Trump aide Steve Bannon and White House chief of staff Reince Priebus attempting to strangle one another.

The Simpsons' Trump says in the clip: "One hundred days in office. So many accomplishments. Lowered my golf handicap, my Twitter following increased by 700, and finally we can shoot hibernating bears – my boys will love that."

And the president's animated hairpiece also features.

The cartoon also imagines Trump's eldest daughter Ivanka Trump replacing Ruth Bader Ginsberg as a Supreme Court Justice, and features the president reading a book entitled 'The Little Book of Bombs'.

It culminates in an advertisment stating: "100 days – we are 6.8% of the way home. Paid for by anybody else 2020."

The episode, which airs on Sunday, is not the first time The Simpsons has poked fun at Trump. In a previous series, the cartoon mocked Trump's presidential campaign.
