Prank Call of Cthulhu: And then, after the tune ends but before it starts up again, there's a single spoken word: "HELLO??" It's weird.

LOL. That's awesome. Either I've heard that truck or one that has the same song sample. It was back in 2000 somewhere near Seabrook, Texas. I was in a park with my girlfriend and we were both weirded out by the "HELLO?!" Enough so that I remember it 12 years later.

"Hello, folks!"
