Mike Tyson was a guest on The Tonight Show Starring Jimmy Fallon, where host Jimmy Fallon decided it was time to find out what happens when Mike Tyson fights Mike Tyson…in video game form.

Fallon had the classic Nintendo boxing game Mike Tyson’s Punch Out!! all set up on the big screen, and the final fight with Tyson (thanks to the 007-373-5963 code, of course) ready to go.

You can see how the former champ fared in the video below.

Josh Brolin made an appearance last week on The Tonight Show starring Jimmy Fallon to promote his new movie, Sin City: A Dame to Kill For, and host Jimmy Fallon brought up the first film the actor was ever in — The Goonies, which celebrates its 30th anniversary next June. Brolin said he would participate in a sequel if it actually happens (there’s been many rumors about it over the years) and then he donned a red bandana like his character, Brand, wore in the 1985 Richard Donner film.

Check out the video interview here below.

For the longest time, people have been saying that comedic actor Will Ferrell (Anchorman, Step Brothers) and Chad Smith, the drummer for Red Hot Chili Peppers, look like one another. These two make every “celebrity lookalike” list ever made. But while those lists oftentimes really stretch in their celebrity comparisons, the Will Ferrell/Chad Smith pair is spot on – these dudes really look like twins.

So, last night, the two men made an appearance together on The Tonight Show featuring Jimmy Fallon where they had a drum battle!!!

Watch the video here below of the drum-off, as well as the video of Fallon interviewing the two men – and as you can imagine, it was very hard for Fallon to not fall over laughing.

On last night’s The Tonight Show Starring Jimmy Fallon, host Jimmy Fallon and the show’s house band The Roots got together for another one of their “Classroom Instruments” performances. This time around, they were joined by Tony Award-winning performer Idina Menzel, or as the whole world knows her now thanks to John Travolta — Adele Dazeem.

For this installment of Classroom Instruments, the gang did a special rendition of “Let It Go,” from Disney’s Frozen, which Menzel sings in the film.
