From George Clooney planting a smooch on Billy Crystal to “The Artist” proving silence really is golden (yes, that is the most overused phrase of the Oscars season) the 84th annual Academy Awards had plenty of memorable moments.

George Clooney kisses Billy Crystal (and other hilarities in the opening montage)

Billy Crystal kissed George Clooney, was wished good luck by Justin Bieber and jumped out of a building -- and that was all in the opening montage.

In a hilarious spoof of the movies nominated for best picture, Crystal famously inserted himself in some of the films’ most famous scenes.

In a mock scene from “The Descendants,” Clooney leans over the bed to kiss his comatose wife, who is actually Crystal. (Later in the show, Crystal told Clooney’s real life girlfriend Stacy Keibler she’s a lucky girl as Clooney is a very good kisser).

Canada’s own Biebs also made an appearance in a spoof of “Midnight in Paris.” Shown in a vintage car with Sammy Davis Jr., Bieber said he was “here to get the 18-24 demographic.”

Crystal then launched into a song and dance routine that although predictable, was refreshingly funny after last year’s super stiff opening monologue by Anne Hathaway and James Franco.

Octavia Spencer’s emotional win

A verklempt Spencer could barely get the words out when she accepted her first ever Academy Award for best supporting actress for her role as Minny Jackson in “The Help.”

“Oh, thank you,” she managed to say as she fought back tears. “I share this with everybody.”

Billy Crystal was also touched by her emotion and commented, “(This is) what the Oscars are all about.” He went on to say when he saw “The Help” he liked it so much he wanted to hug the first black woman he saw, which from Beverly Hills, is about a 45 minute drive. Um, not sure if we should laugh at that one.

Emma Stone’s first time

“This is my first time presenting an award,” said a glowing Emma Stone as her co-presenter Ben Stiller stood motionless. Stone, who was one of the best dressed of the night in a red Giambattista Valli gown, said to Stiller they needed some banter. She danced around, while he remained stone-faced (a spoof on Hathaway and Franco’s co-hosting last year perhaps?), and then launched into a song about the nominees and even invited Jonah Hill up to dance.

Stiller replied with “I get it, you’re new. You’re perky. It gets old fast.” She reminded Stiller about past shows where he sported a green motion capture suit and donned blue body paint to be an “Avatar” character.

She said she was surprised he didn’t go full “Planet of the Apes” this year and he broke his veneer and countered that they couldn’t have it ready in time.

Canadian Christopher Plummer wins his first Oscar and wins the classiest speech of the night award (if only that was a category)

Toronto-born Christopher Plummer became the oldest actor to ever win an Oscar at the age of 82 for his portrayal of an elderly father who comes out as gay man in “Beginners.”

After a standing ovation from the crowd, Plummer lovingly looked at his new golden statue for best supporting actor and said, “You’re only two years older than me, darling. Where have you been all my life?” He also said he’s been practicing his Oscars speech since he emerged from his mother’s womb.

After thanking The Academy, his fellow nominees and Ewan McGregor, he finished off his touching speech with a heartfelt thank you to his wife Elaine, who “deserves the Nobel Peace Prize for coming to my rescue every day of my life.”

His classy speech was the best of the night hands down.

Ferrell and Galifianakis ‘crash’ the Oscars

There may not have been songs performed at this year’s Oscars, but Will Ferrell and Zach Galifianakis tried to make up for it by creating a little music of their own.

Dressed in white tuxedos and crashing cymbals together, the actors told the audience as “serious musicians, it is our pleasure to step out of our day jobs to present the Oscars for best original song.”

Zach said the winner of the category will join such great songs as “Moon River,” “When You Wish Upon a Star” and … “It’s Hard Out Here for a Pimp.” CLANG!

They then fumbled with the cymbals as they tried to read the card and presented the award to “Man or Muppet” from “The Muppets” to fellow funnyman, “Flight of the Concords,” Bret McKenzie.

‘Iron Lady’ becomes the ‘Golden Lady’

Meryl Streep took home her third Oscar for best actress for her role as Margaret Thatcher in “The Iron Lady.” She’s been nominated 17 times and hasn’t won since 1982 so the win was more than well-deserved. But Streep didn’t think everyone would see it that way. “When they called my name I could hear half of America going, ‘Why…? Her? Again?’ But whatever,” she joked.

After thanking her husband and her makeup artist, she said a touching thank you to all her colleagues and friends.

“I look out here and see my life before my eyes. My old friends. My new friends. Really this is such a great honour but the thing that counts the most with me is the friendship and the love and the sheer joy we have spent making movies together. Departed and here.”

Silence speaks (a.k.a. Jean Dujardin wins Best Actor) 

Silence really did beat sexy when Jean Dujardin took home the best actor Oscar for “The Artist,” beating out the likes of George Clooney and Brad Pitt.

“Thank you! I love your country,” said an excited Dujardin, who portrayed a silent film star in the film. Not since 1929 has a silent movie won and Dujardin told the audience that during that first Oscar ceremony, tickets cost $5 and it lasted 15 minutes.

He finished his speech by saying if his character George Valentin could speak he would say “Wow! Formidable! Merci!” (And a bunch of other French words that he said really fast and we didn’t quite catch).

“The Artist” also took home best picture and best director for Michel Hazanavicius, as well as two other awards, proving that silence really is golden (sorry, couldn’t resist).
