John Mulaney has written many SNL bits but "Diner Lobster," which is featured on his hosting gig episode, might just be his crowning achievement on the series. Mulaney guest stars as a diner waiter who gets a strange request from a customer (Davidson) for a lobster dish. What ensues is an uproarious musical number with Kenan Thompson and Kate McKinnon as a dramatic lobster father-daughter duo singing of their impending deaths. Davidson has a hard time keeping a straight face here, but honestly, we'd be in stitches as well. Plus, his breaking makes the sketch even funnier, to be honest.
