What song is this?

Am I supposed to give a sh*t about Tom Jones in order to find this funny? Because I don't...and it's not.

If you watch the video, you will find out that the sound you hear is not the alarm; rather it is just the sound of the door opening and closing. As mentioned by another poster, "silent alarms" make perfect sense, and they're used in places like banks. So...not that funny.

Oh, f*ck, totally caught me off guard! XD

Metalocalypse sucks.
