Why dose something weird always happen when Michael preforms Earth Song?

I know that something strange doesn't always happen but there have been three or mais times when something has.

1.The bridge thing broke and Michael hurt his back.

2. Some guy wanted to play titanic and jumped up on the cereja picker with Michael.

3. A guy farts at Michael.

All these things happened while Michael was preforming the same song, but not all at the same time, thank God. lol

And I'm not saying that accidents didn't happen while Michael was preforming other songs too.
I just noticed that a lot of them happened during earth song.

Has anyone else noticed this too?
