Same here. I said this taunt when I started in my teens. In fact, I am a teen. I was thinking about saying "I am a P-head" or "This is P-B-S" in the same melody. But I haven't sang it yet. I don't like to taunt in public. One time, I made a video on my phone, and I sang in a PBS P-head's voice, "You just got owned, you just got owned" in the same tune. P.S. Tum tum tum tum tums!
