Prepare yourself: The latest viral music hit has arrived. It’s called "The Fox,” a hilarious and maddeningly infectious song by Ylvis, a pair of Norwegian variety show brothers. The video, which involves people dressed up as animals dancing around in the woods while Bård and Vegard Ylvisåker croon ”dog goes woof/ cat goes meow/ bird goes tweet/ mouse goes squeak,” has acquired nearly 3 million hits on YouTube in three days. If you’ve already seen "The Fox,” it’s probably left you with plenty of questions of your own. Like, "Why am I still hopelessly stuck on the insanely catchy clutches of a song about animal noises?” and "Should I be reevaluating my own understanding of animal noises? Do elephants really go … "toot”? And of course, the most important question of all: "Wait, seriously, what sound does a fox make?”

The campy and comical video shows Perry fighting a tiger, painting an elephant's toenail and swinging through the jungle, but the video takes on a much deeper meaning. "Roar" kicks off this new chapter in a her career, and in it, she proves that she's no longer a scared girl; she's empowered, fierce and has found the strength to overcome all adversities. MTV News breaks down the five key scenes to the "Roar" video.

The appearance of the first trailer for José Padilha's Robocop heralds yet another remake of a bravura Paul Verhoeven sci-fi film from the 80s. The film-going public can't really win in this situation. If the new version turns out to be a pale imitation of the original's bombastic, gorgeously grim satire on corporate America, we've all paid to see a duff movie. If Padilha pulls off a miracle and delivers the sleek and visceral reworking hinted at here, you just know they're going to bring back Showgirls next.
