Fallon is throwing his best punches on his debut week as host of ‘The Tonight Show’ with a return skit which was made viral by Fallon and BFF Timberlake. Recreating the exact same opening as the previous #Hashtag video, Jonah Hill joins in on the fun on #Hashtag2. Both kick it old school and reminisce on memories and even hashing old school hip hop lyrics. And of course we get some special guests join in at the end.

Fallon is killing it so far on ‘The Tonight Show’, and we still have a whole Fallon/Timberlake episode this Friday; which will surely be hilarious.
