Jimmy Fallon And Justin Bieber's Secret Handshake Puts All Others To Shame

Waving is for borings.

On Thursday night's episode of "The Tonight Show," Jimmy Fallon and Justin Bieber instead greeted each other with an elaborate, not-so-secret handshake that included elbow grabs, fake barfing, and a finger-snap version of popcorn popping.

Friendship.

In our humble opinion, the handshake is only fitting of Fallon and Bieber's relationship, which has been known to get some people (ahem) a little emotional. While a guest on "The Tonight Show" in September, Bieber opened up to Fallon about shedding tears after his VMAs performance.

"It was just so overwhelming for me, everything ... I wasn't expecting [the audience] to support me in the way they did," the singer said, recalling that he'd been booed the last time he'd performed at an awards show. "I've worked so hard at this album, I've worked so hard at becoming the man I want to become ... I just put everything on the line. "

"I've known you for a long time and I always support you," Fallon said."You went out there and you just really did a great job."

Earlier this week, Bieber performed his hit single "Sorry" as Fallon's musical guest.
