Strange Mac Book Pro Phenomonom

Something very strange happened last night while I was using my Mac Book Pro (MBP).

I was watching a film on front row, once it ended I heard a background noise as if the film was still playing. I close all my apps down but it was still there. I concentrated on the sound and realized it sounded like 2 or 3 distinct radio/tv broadcasts, some in English, some in other languages, I removed all network cables and other connections to make sure it was nothing coming down the Internet, I moved to another part of the house and it went away, I move back and it came back.

I can only conclude that because the MBP is made out of aluminum some how it was acting as an aerial for radio/tv broadcasts and piping the sound through my headphones.

I emailed apple about this lets see if they respond!
