Leave it to Katy Perry to squeak out a song of summer contender right at the last second. Her video for "This Is How We Do," a cut off her third full-length album, PRISM, is an all out onslaught of summer fun. Day drinking and karaoke? Check. Going to bed with a 10 and waking up with a 2? Check. Twerking ice-cream cone? Check! Throw some Pee-Wee backup dancers and getting so blotto that you leave your car at the club valet and you've got the recipe for the perfect summer.
