This photo seems to suggest it may be the Sex Shark himself, Noah Puckerman (Mark Salling). Pictured with the holiday episode director, Adam Shankman, and Jacob Artist (Jake Puckerman), one of Mark’s formidable guns appears to be emblazoned with a Star of David. As far as we know, Puck is not currently representing Israel on his deltoid IRL, so we’re guessing that is a fake tattoo. Considering the fact that Jake and Noah will be singing a Hanukkah duet together, could it be that they’re both getting tattoos to celebrate their Jewish heritage?
Unfortunately, we can’t see Jacob’s arm well enough to say for certain, but it does sound like the way a couple of Puckermans would bond!
