What Katy Perry lacks in originality (just because it's spelled "Gurls" doesn't mean we'll forget about the Beach Boys) she makes up for with a Snoop Dogg rap and a sexed-up, Candy Land–themed video in which she wears a bra that squirts whipped cream. The lyrics could use some work ("The girl's a freak/ She drives a Jeep"?), but they didn't keep Perry from dominating this summer with her anthem about West Coast girls and their hot, tanned skin.
