Aquaman star Jason Momoa gets a surprise – and lands an even bigger one smack across Beck Bennett’s face – in this week’s Saturday Night Live promo.

In the video, this weekend’s host arrives at 30 Rock ready for work. Unrecognized by an NBC page, Momoa is recruited to temporarily man the front desk, and the former Game of Thrones star takes the new gig very seriously indeed.

Spoiler alert: Momoa gets his answer. Check it out above.

This weekend’s musical guest is Mumford & Sons. Matt Damon will host SNL on December 15 with Mark Ronson and Miley Cyrus as musical guests.
