When I can't wake people up in my house....Throttle test! When I was single and had a girl spending the night I would preset Bullet for my Valentine's "Her voice resides" which begins with an all out thunderous scream, distorted drop D open guitars and loud druming intro... Oh Man, they jump right out of bed every time.
... That would be preset on alarm 2 after alarm 1 wakes me up. Alarm 2 goes off 30 minutes later so after my shower in the morning I get my first laugh as I wait for 6:30 to hit then "Awwwwwwww!!!!!!!!"
you'd have been disappointed at my reaction then. I can sleep through anything.
