Since its premiere in 1975, Saturday Night Live has given us way too many iconic moments to count. Think of a famous comic actor of the past few years, and it's very likely they will have got their start on the late-night variety show.

But, more recently, one moment on SNL has not only triggered the masses but led to a secret service investigation into John Mulaney.

Here's the full story...

SNL is arguably one of the most popular shows on TV.

When it comes to original comedy, there's really nothing better.

The show has a rich history.

It first launched in 1975 and has starred a recurring cast of talented comedians and celebrities ever since.

The show is responsible for launching many careers.

Tons of hugely popular comedians and actors got their start on SNL, including Amy Poehler, Kristen Wiig, Tina Few, Will Ferrell, and Pete Davidson.

It's also given us some of the most famous sketches of the past decade...

Like Alec Baldwin's iconic take on Donald Trump, for example.

And of course, they're well known for ruffling feathers.

Comedy always comes at a price and in the age of "cancel culture", it can be hard to know where to draw the line.

While some comedians opt to stray away from sensitive subjects...

Others embrace them wholly.

And what better show to be controversial on than SNL?

Recently one moment on the show caused some serious controversy...

John Mulaney hosted the show back in October.

And some of his jokes were that controversial, they triggered a secret service investigation.

Mulaney hosted the show way back on February 29th...

And, with it being a leap year, he made a rather topical joke.

He joked about Julius Caeser's murder by senators on the same day.

And followed up with: "That would be an interesting thing if we brought that back now!"

This week, Mulaney opened up to Jimmy Kimmel about the joke's consequences.

"I guess they opened a file on me because of the joke, and I have to say: Am I stoked there’s a file open on me? Absolutely. Did I enjoy it in the moment? Not so much," he said.

Luckily, the case has now been closed.

So maybe the secret service can take a joke afterall...

What a bizarre story.
