Watch Justin Bieber & Jimmy Fallon Show Off Their Incredibly Long, Insanely Complicated Secret Handshake!

This is too good!

Justin Bieber was just randomly roaming the halls of The Tonight Show on Thursday night — well, OK, he was there as a guest (LOLz!) — when he ran into Jimmy Fallon right in front of The Roots‘ dressing room.

Just like any good bros, the two proceeded to say hi to each other with the Longest. Handshake. Ever.

Seriously, though — if you’re asking us What Do You Mean, let’s just put it this way: we played the Biebs’ new album, Purpose, in its entirety during the choreographed routine! Ha!!

Bieber sure didn’t seem Sorry about taking up so much of Fallon’s time, either!

Ch-ch-check it out (above) to see the whole thing go down! Favorite part? Definitely grabbing the elbows! LOLz!!
