Watch 'SNL' Season 51 finale stuns viewers with dark explosive joke

Saturday Night Live has finished season 51. But with the ending, it threw several dark jokes.

One of them featured in a brutal Oval Office skit.

It featured a parody of President Trump and sex offender Jeffrey Epstein.

Sitting behind the Resolute Desk, Trump was visited by Epstein rattling chains.

When Trump tried to high-five, Epstein, in response, delivered a dark punchline.

"You know what, this time, I’m going to leave you hanging," he says, referring to Epstein’s death in jail.

Other jokes include Trump in an awkward manner asking Epstein what heaven was like.

Will Ferrell, who was playing the disgraced financer in a deadpan way, said, "It's really, really hot."

Paul McCartney swoons SNL viewers

Paul McCartney, a legendary singer, stunned fans with swooning songs on Saturday Night Live.

The Beatles icon performed his new track, Days We Left Behind.

In addition, he also belted out the hit song Band on the Run with Chad Smith.

Then, McCartney delivered an unforgettable performance by reuniting with his band.

Together, they performed Coming Up, a hit track from the 1980s.

McCartney previously performed on SNL on May 17, 1980.
