These days, Saturday Night Live is at its best when it’s being unapologetically weird, like with “Space Pants” or the initial David S. Pumpkins sketch, and former writer John Mulaney appeared to be very conscious of that fact during his first-ever hosting gig on the show last night. The two best sketches from last night were delightfully bizarre, with one involving an elaborate Les Misérables homage about lobsters and the other focusing on the incestuous ramifications of a wacky body-swap sitcom. You can see “Diner Lobster” up above, and you can see “Sitcom Reboot” below.
