Jimmy Fallon's 10 Best 'Late Night' Moments (Video)

From "History of Rap" to "Slow Jamming" the News, the host made the 12:35 a.m. time slot his own.

Jimmy Fallon is hours away from his final Late Night, which since 2009 has been home to epic collaborations with Justin Timberlake, slow jams of the news, and parodies of Downton Abbey and Breaking Bad.

Fallon, who takes over The Tonight Show on Feb. 17, began making his mark with early segments such as 7th Floor West, his soapy look at life inside the talk show, and the oddball Robert Pattinson Is Bothered – where he played a tree-dwelling Robert Pattinson. He also became obsessed with organizing TV reunions – and managed to get various members of Saved by the Bell, The Cosby Show and Full House together.

In the past year he's convinced First Lady Michelle Obama to recap the evolution of mom dancing, Tom Cruise to crack an egg on his own head, and Harrison Ford to pierce the host's ear, among other awesome TV moments.

Fallon's final episode airs early Friday, beginning at 12:05 a.m. ET.

Below The Hollywood Reporter counts down ten of Fallon's bet Late Night bits.

History of Rap

There have been four volumes so far of Timberlake and Fallon's History of Rap, most recently in March 2013. Let's hope for a fifth installment on The Tonight Show.

President Obama Slow Jams the News

Fallon not only landed the President as a guest, but he also got him to make student loan policy a little more sexy. Last month, Gov. Mitt Romney became the latest to slow jam the news.

Mark-Paul Gosselaar as Zach Morris

Fallon worked hard to reunited the cast of Save by the Bell. And while it never happened in full, getting Mark-Paul Gosselaar to come on the show in character – blonde hair and all – was something to behold.

Egg Russian Roulette

There are a dozen eggs. Eight of them have been hard boiled and four of them are raw. Fallon went head-to-head with the likes of Edward Norton, Tom Cruise and David Beckham during his Late Night tenure. Below he faces off against his Late Show successor, Seth Meyers.

Thank You Notes

Fallon wrote thank you notes every Friday, most recently sharing why he was thankful for Jay Leno.

Robert Pattinson Is Bothered

At the height of Twilight-mania, Fallon played an Edward Cullen-like version of Pattinson, sitting in a tree to brood about what most annoyed him. In 2010, Pattinson himself showed up to reveal just how bothered he was by Fallon's impersonation.

Joking Bad

Fallon became the king of event-sketches, teasing them for weeks at a time until they were unveiled. Ahead of Breaking Bad's finale, Fallon donned a bald cap and whitey tighties to pull off Joking Bad. Breaking Bad stars Aaron Paul, Bryan Cranston and Bob Odenkirk took part too.

Sticky Balls With Channing Tatum

No other late night host has gotten his guests to play so many whacky games. Among them: playing sticky balls with Channing Tatum and beer pong with Betty White.

Springsteen Collaborations

The musically-inclined Fallon loved playing Neil Young and jamming with Bruce Springsteen. Below, the pair folk out Willow Smith's "Whip My Hair."
