Tired of musical monologues? Too bad — since Bruno Mars is Saturday Night Live‘s host and musical guest this week, you should be prepared to see song and sketch collide all night long. That’s certainly the case in these promos, which pair the doo-wop hooligan with fellow musician Fred Armisen. (The SNL castmember played  drums professionally before turning to comedy.)
