Jimmy Fallon and Justin Timberlake take hashtags to the hilt before being interrupted by ?uestlove in their #Hashtag sketch from Late Night With Jimmy Fallon. The real time demonstration of a Twitter exchange proves how ridiculous the term – and other overused social media acronyms – sound in actual conversation.

Fortunately ?uesto is there to curb their enthusiasm with a hashtag of his own. Check the footage below to watch Jimmy Fallon and Justin Timberlake #Hashtag their hearts out. Stay tuned for more.
