It's a mark of shame for 'SNL' guests to crack up in the middle of a sketch, but for Alec Baldwin, someone who's more or less been in the cast these past four years, he's known for being pretty much ice cold.

Until now, that is.

He made his way through countless sketches as Donald Trump, but it's only now in his final few weeks (hopefully) of playing the US President that he's finally cracked up during a sketch.

This week's Cold Open saw the duelling Presidential Town Halls between Joe Biden, played by Jim Carrey, and Alec Baldwin's Trump recreated as people flipping through channels. As you'd expect, Biden's Town Hall was like an episode of 'The Joy of Painting with Bob Ross', while Donald Trump's was a wrestling match.

Take a look. Baldwin cracks up around eight and a half minutes in.
