This is a video of Youtuber Buddy Crotty lulling his crying baby daughter back to sleep with the sound of Darth Vader's breathing. It's pretty effective. When I was a baby my parents used to lull me to sleep with the sound of heavy metal and now I can't go to a concert without falling asleep in the mosh pit and getting my arms torn off.
Hit the jump for the video.
Thanks to my buddy Brian, whose parents lulled him to sleep with the sound of running water and who still has a bed-wetting problem to this day.
