Somewhat ridiculous ways to calculate PI number

I've found description of experiment to calculate PI number as a result of physical Monte Carlo simulation by shooting shotgun pellets over quarter of circle marked inside square. At least it is great visual explanation how to calculate PI.

I remember that I saw other technique using pins tossed over parallel lines. I've searched that and found something much more ridiculous: Calculating Pi by Throwing Frozen Hot Dogs

I don't dare for searching any more of that today...
