It was a week of change on "Saturday Night Live."

Two new hosts got broken in this weekend, as "Big Bang Theory" star Jim Parsons hosted the show for the first time and Colin Jost took over as co-anchor of "Weekend Update," replacing six-year host Seth Meyers.

Jim Parsons did a perfectly acceptable job hosting, sticking mostly to his wheelhouse of awkward, put-upon characters — with the notable exceptions of Peter Pan and a child actor.

He did a sing-talking musical number for his monologue, stating that he didn't want to be just known as his über-nerd character Sheldon Cooper. He was joined by Jaleel White, Jason Alexander, Bill Cosby, Henry Winkler, and Angela Lansbury (Jay Pharoah, Bobby Moynihan, Kenan Thompson, Taran Killam, and Kate McKinnon, respectively), who are also permanently associated with their TV characters.

Jost was also fine on his first night as anchor. He's been a writer on "SNL" for the last nine years and co-head writer since 2012, so he's certainly earned the spot. But even though it's too early to knock him for his unimpressive performance in the role, a look at a stand-up spot from a year ago suggests there's probably not much more to look forward to in terms of personal style.

Jost was the editor of The Harvard Lampoon, which is synonymous with dry, cerebral humor. That makes the choice to go with the forgettable joke reader as anchor instead of the personality-driven style of Chevy Chase or Dennis Miller or Norm Macdonald understandable, but also disappointing.

BEST USE OF THE GUEST:

Yes, school plays are awful, but there's a special kind of awful reserved for kids who really, really want to act. Those kids end up at “Spotlightz! Acting Camp for Serious Kids!” and it's magnificent. Parsons does his least Parsons-like work as a child actor doing a terrible George Clooney.

Everyone in the sketch gets to indulge their worst impulses for chewing scenery and mugging as these kids perform scenes from this year's Oscar nominees, but Vanessa Bayer steals the show with her frighteningly bright smile and the line, "I've got an idea: Let's sell drugs! To help our AIDS!"

GORDITA VS. CHALUPA:

Someday, the Oxford English Dictionary will rank the funniest words in the English language, and there's no doubt that those two will top the list. By their entries will be both of these "SNL" sketches. Aidy Bryant's grotesque fairy Tonkerbell talking about "gorditas, a strong masseuse or very loose underwear," is as delightful as it is horrifying.

And Pharoah's Shaquille O'Neal thinking Thompson's Charles Barkley held a gun on him when, in fact, it was a chalupa nicely buttons an otherwise uneven "Update" appearance. To be fair, it's got to be hard to read cue cards with your eyes crossed like that, but dropping lines on live TV is never a good idea.

WEIRDEST NON-USE OF SASHEER ZAMATA:

There's a fine line to walk when you've only got one black woman in the cast. You don't want to put her in every generic, non-speaking black girl role, but also her absence is conspicuous in, say, a "Soul Train" scene where Kate McKinnon almost ruins the joke of an "inconspicuous" serial killer hiding in plain sight on TV dance shows by playing a second white person on an almost 100-percent black show. Parsons plays a great serial killer, which was probably because it's just Sheldon Cooper with more eye contact.

THE COMMERCIAL PARODY:

"Bird Bible" is exactly what it says it is: an illustrated Bible with birds. Bird Jesus, bird Adam and Eve, and bird David standing triumphant over a decapitated stork Goliath. McKinnon and Mike O'Brien nail the dead eyes of late-night infomercial actors. It's crazy weird, but also hilarious. Also, it feels like that book probably exists somewhere — maybe in a discount store in the South, or your creepy aunt's attic.

WORST IMPRESSION:

Taran Killam's Henry Winkler sounded like William Shatner. This is, of course, a completely unfair judgment, as he only has four words to create the character, but sketch comedy is a cruel mistress.

He makes up for it later with his Jebediah Atkinson character, tearing into this (and every) year's Oscar nominees. Though even the most curmudgeonly of critics isn't immune to the charms of "The Lego Movie," apparently.

BEST USE OF SASHEER ZAMATA:

"12 Years Auditions" has Parsons, Brooks Whelan, and Mike O'Brien as uncomfortable white actors auditioning for the role of "Hostile Slave Owner," the high point of which is O'Brien recoiling from Zamata handing him a whip. Bobby Moynihan does a mighty convincing racist guy who walks in off the street.

THE OTHER BEST LINES OF THE NIGHT:

"Now it smells like old dookie in a bag and new dookie in pants."

"I don't think he's gonna want a naked man flying out of the dirt at him."

"Nobody wants it until they get it."

"My mother is a school teacher and my father is a Christmas ornament."

"Saturday Night Live" airs Saturdays at 11:30 p.m. on NBC.
