How do you handle Sideshow Bob?

I didn't think there was an impact of if you tap him or not on anything other than your righteousness rating. Assuming this is why the question is being asked. As far as I understand it side show bob has X chance of showing up every time you visit yours or someone else's SF. So theoretically you and everyone of your friends could all visit your SF at the same exact time or within minutes of each other and all tap him if everyone's dice roll was in that X chance range.
