Louis CK and Kate McKinnon got a serious case of the giggles on SNL last night

The joys of live TV.

Louis CK was the special guest on Saturday Night Live and as per with guests on the show, he starred in a few sketches.

But there was one sketch that ended up being funny not so much for the content, but for its stars.

Louis, alongside series regular Kate McKinnon, played re-enactors showing what life was like in a 1913 apartment.

But about a minute in, Kate can't hold it together and breaks - as does Louis.

The results are brilliant.

To be fair, we cracked up at Louis' accent too.
