Perhaps the biggest surprise of Jimmy Fallon's first week of hosting The Tonight Show was how familiar it was. He might be hosting the most hallowed talk show property in the medium's history, but it felt a lot like his younger, looser Late Night—albeit with enough clout to stick U2 on a roof to belt out their latest (entirely forgettable) single.

For fans of Late Night, the first week of Tonight Shows was a relief: It's the same guy after all! The Roots are still around! Viewers used to Jay Leno, though, they likely wondered exactly what it was they were watching, and why it was so much funnier. If you stayed away for fear of Fallon playing it a little too straight, don't worry. We've got the best bits from his surprisingly polished first week right here.

Big-Name Guests

Michelle Obama's appearance on Thursday was a particular highlight, but the lineup of celebrities appearing throughout the week was pretty impressive: Will Smith, Bradley Cooper, and Kristen Wiig all showed up on the couch, while U2, Arcade Fire, and Lady Gaga provided the sounds. More importantly, though, how often do you see Jerry Seinfeld do stand-up these days? As far as first weeks go, it was a successful sign that Fallon's Tonight Show will be a destination for faces you won't see everywhere else on the interview circuit.

The Evolution of Hip-Hop Dancing

One of a number of Late Night skits making a reappearance on the new show—see also the #Hashtag2 sketch with Jonah Hill—the Evolution of Hip-Hop dancing was an odd mix of nostalgia for the target audience (The Kid'n'Play!) and, for the older audience tuning in to see what the new kid is about, an introduction to all manner of dances they'd probably never seen before. Jimmy Fallon: building generational bridges since...*checking watch*...2014!

The History of Rap 5

Another welcome return from Late Night, Friday's special guest (and regular Fallon partner-in-crime) Justin Timberlake didn't disappoint during his appearance, teaming up with Jimmy for one more race through hip-hop history. Highlight of this particular installment? The two times Timberlake stopped to throw shade on Fallon's cover versions.

Sorry, Buffalo

At this point, Timberlake and Fallon make such a great double act that we'd be perfectly happy to see Justin give up that whole internationally-adored pop star thing to join the show as a regular sidekick (no offense, Higgins). If nothing else, he's always got a side business issuing public apologies to spurned cities.

The Ragtime Girls Perform "Ignition (Remix)"

Turns out a barbershop quartet version of R. Kelly turns out to be so damn catchy that it supports a one-joke concept. Take note, would-be Sing-Off participants.

Brian Williams Raps "Rapper's Delight"

This video went viral online the day after the show's premiere, and deservedly so. Again, it's a silly one-joke sketch, but again, it's something that works because the idea is so silly, and it's done so well. Also because we can all imagine that Brian Williams would be very much up for trying to recreate this live if asked. (Seriously, it's getting a little depressing how much he wants us to think he's funny.)

Kristen Wiig Pretends to be One Direction's Harry Styles

What exactly led to this bit, in which Wiig spends the entire interview pretending to be teen heartthrob Harry Styles, is likely to remain a mystery for a long, long time, but we're not complaining—especially when she tries to sing "You're Beautiful" despite having clearly never heard the song before in her life. We can only hope that this leads to a new recurring bit where a celebrity pretends to be another celebrity they know nothing about.

Celebrity Charades

Another element carried over from Late Night, and it's obvious why: The idea of watching celebrities embarrass themselves playing games that we all know and, to varying degrees, love, is a very appealing one indeed—especially when they're as bad at it as Bradley Cooper. In related news, anyone who doesn't want Emma Thompson on their charades team is completely insane.

The Roots Re-enact The Bachelor

It's hard to say which was more entertaining: the dialogue reproduced faithfully from the guilty pleasure reality show, or Questlove's bravura acting performance. If the real Bachelor was this entertaining, we'd be tuning in every week. (Skip to 0:40 to get to the skit directly.)

Downton Abbey Skating

Why? We don't know, and we don't want to. All we really want to do is watch.
