Question regarding Foosball

I'm way behind the community in most things so maybe this is something you all know about. First time it's ever happened to me though. My Sim was visiting with the PartyHaus household and they were all sitting in the living room talking. The foosball table in the corner basically started "playing" itself. The ball was bouncing around the table as if someone was playing but the nothing else was moving, just the ball bouncing around the table by itself. Anyone ever had that happen? I don't think it was a ghost.
