Phone conversation gone weird?

Question

I was talking to two of my friends with a conference talk on Skype. About an hour into the conversation it was like someone had tapped the line and there were weird sounds going on for like, an hour. It started with helicopters and gunshots, then played really weird music, involving a really high voice singing "It's a wonderful day in the neighborhood" Does anyone know what it could have been?

Answer 1

Someone was playing Call of duty and watching Mr Rogers Neighborhood while listening in on your convo. lol

Answer 2

Probably radio or T.V. interference.
