Let's throw it back -- 17 years back -- to 1999 ... to a little tune by Sisqó called "Thong Song." This delightful jam by the majestic platinum-haired R&B singer has been responsible for making us party like it's 1999 since the song came out. Fast-forward to 2017, and Panic! At The Disco teamed up with Sisqó to perform the song together. And it is everything.
Panic! At The Disco appeared on "Jimmy Kimmel Live!" to perform "Thong Song" with Sisqó ... AKA Panic! At The Sisqo. Brendon Urie kicked off the song before Sisqó joined him on stage to sing his chart-topping late '90s classic. And perform all of the choreography we know and love from the original music video.
He's still got it, guys:
