Note to all you about-to-be-marrieds: You DO NOT have to do this at your reception in order to have a good time. No need to keep up with the Anatevkans here. But kudos to the whole team who pulled it off.
FYI – if you ARE going to try and replicate this, there’s a hairball hacking “ch” sound in the middle of “L’Chaim.” Otherwise you sound like a total goy.
