Can Justin Timberlake just do a whole season of "Saturday Night Live" already!

On Tuesday's "Late Night with Jimmy Fallon," the singer performed one of his most famous songs with a twist: By bringing back the barbershop quartet known as the Ragtime Gals to sing "SexyBack."

We almost like this version better than the original ... almost!

Fallon joined Justin onstage for the hilarious cover and the two definitely seemed like they were having some fun together.

How do you think the 32-year-old would do as an "SNL" regular? Sound off below and watch his adorable skit above!
