'The Wizard of Ahhhs' Puts an a Cappella Spin on the Classic Film

Toto, we're not in Kansas anymore — we're in a Pitch Perfect movie.

Todrick Hall, the mastermind behind viral videos such as Mean Gurlz and Beauty and the Beat, is back again. And this time he's created an a cappella pop medley video inspired by the famous 1939 film The Wizard of Oz.

The a cappella group Pentatonix collaborated on the video. Their inimitable style — five-part harmonies layered over group member Kevin Olusola's beatboxing — helped the group win first place in the third season of NBC's The Sing-Off.

But "The Wizard of Ahhhs" doesn't simply cover the movie's iconic tunes like "Somewhere Over the Rainbow." Instead, Hall features songs from Frank Ocean's "Thinkin Bout You" to Miley Cyrus's "Can't Be Tamed." Even viral hit "Shoes" (Lyrics: "Shoes. Let's get some shoes.") makes an appearance.

And keep an eye out for Hall, who makes a cameo as Oz himself.

1. 1. KONY 2012

   Invisible Children, a movement seeking to end the conflict in Uganda, created the film Kony 2012. They hoped it would accelerate the arrest of Lord's Resistance Army (LRA) leader Joseph Kony, who has been kidnapping and abducting Uganda's youth for nearly three decades.

   With more than 100 million views in six days, Kony 2012 became the most viral video in history.

   The movement, however, ended quite strangely. The video's creator, Jason Russell, was detained in the Pacific Beach neighborhood, with charges of public drunkenness and lewd behavior.

2. 2. Gangnam Style

   Gangnam Style in a nutshell:

   PSY, a South Korean rapper, singer and dancer, jams out for four minutes to an aggressively hypnotic techno track, while surrounded by horses, beautiful women, a carousel, commuters and old people. He also sings from the toilet. So naturally, the video became incredibly popular.

   According to Unruly Media, 29 million shares worth of popular. Here's how it got so big.

   PSY quickly became a sensation, with appearances on the Today show, Saturday Night Psy quickly became a sensation, with appearances on the Today Show, Saturday Night Live and even the United Nations.

   The video even set a Guinness World Record, for the most likes ever on YouTube.

   This German man didn't make quite the splash he was hoping for, when his attempted cannonball ended with a painful thud.

   "Somebody That I Used to Know" is a smash hit itself. In fact, it's one of YouTube's most-viewed clips ever — it's been shared over 17 million times.

   What we love most about it, though, is the parody and cover culture that it has spawned. Check out a ton of covers and parodies of the song here.

8. 8. Best Job

   Right before the London Olympics, Procter & Gamble released an ad praising mothers worldwide, and it's an absolute tearjerker.

   In three days, the video received over 700,000 views on YouTube. It has been shared over 2 million times. The original video can be found here.

   Donna the Deer Lady, as she's now known, called up a local Fargo radio station and demanded to know why the Minnesota and North Dakota departments of transportation "allow these deer crossings to be in such high traffic areas."

   She's since learned truth about deer crossing signs, but not before the video was uploaded to YouTube by the radio station. It went wildly viral, hitting almost 2.5 million views in only 10 days. At this point, it has been shared over 1.5 million times.

    Robert Wilkinson, a 29-year-old from Edson, AB, was arrested by the Royal Canadian Mounted Police for intoxication, and evidently he didn't agree with the charges. After pleading his case in slurred speech, he decided to describe his ordeal by belting out Queen's Bohemian Rhapsody.

    Despite his inebriated state, Wilkinson manages to sing the entire song, accompanied by some serious headbanging and air drumming. The performance has been shared over one million times.
