8 great celebrity impressions of other celebrities

Perhaps the only downside to celebrities' impressions of other celebrities on "The Tonight Show Starring Jimmy Fallon" is that we can't get enough of them.

Last week, when Ethan Hawke and Fallon performed as dueling Bob Dylans, it got us thinking about some of the last decade's best celebrity impressions — especially when they're either coming from stars who aren't primarily known for being comedians, or when comedians are performing them in front of the celebrities they're imitating.

Singers, as it turns out, can be really good at impersonating other singers. Proof? Just last month, Ariana Grande's Céline Dion wowed the "Tonight Show" crowd.

For stars with multiple impressions up their sleeves, Fallon is more than happy to spin the Wheel of Impressions. Christina Aguilera thrived in her fauxdown with Fallon in February, offering flawless versions of both Cher and Britney Spears. (Her fellow coach on "The Voice," Adam Levine, proved equally deft at the game in September, when he gave us the Michael Jackson rendition of the "Sesame Street" theme we never knew we needed.)

And after years of showing off impersonation prowess as a host of "Saturday Night Live" and as a guest on "Inside the Actors Studio," Kevin Spacey proved in October that Wheel of Impressions is tailor-made for him. In addition to admiring the nuances of his Johnny Carson and Bill Clinton, we should all be so lucky to trick-or-treat with that version of Christopher Walken.

Spacey's not the only star with a take on the former commander in chief. In 2013, U2 frontman Bono proved he has one that might be "Even Better than the Real Thing."

Back at 30 Rock, Fallon proved he's not immune to being the subject of mimicry. Just ask his buddy, Justin Timberlake, who played the host during a "Saturday Night Live" sketch in 2013. (It wound up being almost as good as JT's Michael McDonald impression, which he teased at the end of a Weekend Update appearance in 2008, and reprised with Fallon and McDonald himself five years later, when Fallon was hosting "Late Night.")

Speaking of "SNL," Kate McKinnon's Ellen DeGeneres is always hilarious, but it seems to reach another level whenever she mirrors her in front of the host's studio audience. In addition to the way it amuses DeGeneres, it's easy to be impressed by the sheer absurdity of what can best be described as chair acrobatics.

Last but not least, Matt Damon's understated Matthew McConaughey during a 2007 appearance on "Late Show with David Letterman" may be a first-ballot entry into the Celebrity Impression Hall of Fame. Its nuance, delivery and ability to prompt Letterman giggles prove why it's endured for years on end.
