I didn't know it when I got up this morning. But we all know now—this video is on every gay blog—and it's good to know. Swedish marines stationed in Afghanistan lip-synch "Greased Lightening" from Grease. Because, you know, why not? Two things: JoeMyGod suggests you keep your eye on the upper left corner of the video at the 1:00 mark, and... Jesus... look at the damage a misplaced mustache can do to an otherwise stunningly attractive face. Don't let it happen to you, boys.
