Jimmy Fallon, Justin Timberlake '#Hashtag' Skit: 'Late Night' Host Shows Viewers How Silly Twitter Hashtags Sound In 'Real Life' (WATCH)

Funny men Jimmy Fallon and Justin Timberlake take their comedic collaborations to a new level with their newest skit about the silliness of Twitter #hashtags, and how people really sound when they use them.

On Monday's "Late Night with Jimmy Fallon". the best friends performed a skit where they spoke to each other in ridiculous hashtags.

"Hey Justin, what's up?" the skit began.

"Hey Jimmy, not much. #chilling," Timberlake responded to Fallon.

From there, the twosome had some fun with their Twitter-esque conversation. Here's a few #hashtags they spewed off:

Fallon continuing the conversation: "Just been busy working. #riseandgrind #isitfridayyet"

Timberlake's dentist visit: "I just saw my dentist. #bling #dentalcare #cavityfree #thatshowWedo #wegohard #wecantstop."

Timberlake explaining his love for cookies: "#homemade, #oatmealraisin, #showmethecookie."

Fallon responding to cookie love: "#imtherealcookiemonster, #nomnomnomnomnom."

Fallon's never-ending TV show hashtag puns: "#purpleisthenewblack, #iloveyouyoulovemewereahappyfamily, #im38, #dinosaurs, #iceage."

Timberlake making fun of the twerk-tastic Miley Cyrus: "#gottaberaphael, #leonardosucks, #theturtlenottheitalianrenaissancepainter, #monalisa, #isshesmiling, #speakingofsmilingjustsawmydentist, #dentalcare, #cavityfree, #thatshowwedo, #wegohard, #wecantstop."

Fallon continuing the joke: "#wewontstop."

After a long conversation spoken only in hashtags, Questlove ends the skit when he abruptly enters the room and tells the boys, "Hey guys. #shutthef-kup."

Another classic Jimmy and Justin skit, but it's just one of many the comedic geniuses have come up with for the "Late Night" show.

The last skit that had the world laughing was in honor of NFL season starting. Timberlake and Fallon created a montage of End Zone dances, real and fake, for our viewing pleasure.

The singer and his comedian pal poked fun at Tim Tebow, Aaron Hernandez and Manti Te'O. Fallon ended the skit by mocking Timberlake's boy band days, busting out some "Bye Bye Bye" moves from N'SYNC.

Check out both skits in the videos below! "Late Night with Jimmy Fallon" airs on 2:35 a.m. Eastern time/11:35 p.m. Central on NBC.
