There’s an epidemic going around Anatevka and it all started with Perchik. Fiddler on the Roof star Ben Rappaport recently let his Broadway nerd flag fly high as he fully embraced the musical theatre dubsmash. Watch his progression from novice to on fleek in the videos below—many of which include guest spots by his fiancé, Megan Kane.

Dressing room acting pontification during @fiddlerbroadway rehearsal. Perhaps I'll try this method tonight. #waitingforguffman #waitingforperchik

Then when he introduced Adam Dannheisser (Lazar Wolf) to Dubsmash, it inspired these gems.

Still waiting on a Danny Burstein or Jessica Hecht Dubsmash, but Rome wasn’t built in a day. See this crazy cast of characters live in Fiddler on the Roof at the Broadway Theatre.
