I remember playing with Jarts(tm) when I was younger. They came with a plastic ring that you placed on the ground and the object was to throw your Jart(tm) in the circle.

Like horseshoes with a leathal dart about a foot long.

I didn't play that way. Instead, in a stunning attempt to kill myself and prove Darwanism correct, I attempted to throw them as high in the air as I could. Straight up. This often led to hilarious bursts of adrenaline as I would realize the danger I was in and ran for cover.

I never suffered serious injury, but this also never resulted in a lawsuit.
