Sad patrol

The story:

I was sitting in the back seat of my friend's car and my friends and I were all singing a bunch of Metallica songs and I recall singing "sad patrol" really loud and putting an emphasis on the "o" in patrol. My friend driving quickly shut the volume off and said, "What did you just say" and I responded with "Sad patrol" and everyone in the car was cracking up...it was hilarious. For weeks, I was making fun of my self and yes, my friends didn't let me forget that on for a long time.
