The Tonight Show Starring Jimmy Fallon put together another year of late-night TV filled with positive vibes, music, and celebrities letting loose. All of that combined for the show's most-watched clip of 2023.

The year wasn't all good news for The Tonight Show. As much as it tries to create a fun atmosphere on camera, things behind the scenes weren't always so easygoing. Host Jimmy Fallon dealt with allegations of workplace bullying and a toxic environment.

But when The Tonight Show was on top of its game, there wasn't anything like it in 2023. The NBC program continues to produce content not seen on competitors, instead playing to Fallon's strengths.

For proof, look no further than the Tonight Show's most watched clip of 2023. It came in March when Fallon and The Roots teamed up with the cast of The Super Mario Bros. Movie for a viral hit.

Fallon's Tonight Show found a winning formula with these a cappella videos and similar ones using classroom instruments. This particular clip hit at just the right time, using the Super Mario Bros. theme which has fans across multiple generations.

The all-star lineup of celebrities certainly helped. Seeing the Mario Bros. Movie cast in person was a good reminder of just how much talent collaborated on the animated hit.

Chris Pratt, Charlie Day, Anya Taylor-Joy, Keegan-Michael Key, Jack Black, Fred Armisen, and Seth Rogen all joined Jimmy Fallon and The Roots. The video also came out in time to celebrate Mario Day on March 10 (aka MAR10) and has since topped 40 million views on YouTube.

Jack Black's solo at the 37 second mark creates the highpoint in the video. Fans had fun with the moment as well, treating it like the pinnacle of music in a way that Black would certainly appreciate.

Will The Tonight Show Starring Jimmy Fallon top this clip in 2024? We'll find out when new shows return in January.
