PHILADELPHIA (CBS) - Did you know that trampoline is an Olympic sport? I know, crazy. You know what else is crazy? Not taking precautions to prevent injuries and, oh, yeah, lawsuits if you have a trampoline.

Next to getting hit in the crotch by a baseball bat, nothing spells comedy on America’s Funniest Home Videos quite like a fat guy jumping through a trampoline. Luckily for the trampoline owner, those fat guys sent the video to the tv show rather than to a lawyer.

When you buy a trampoline and let your kids play on it, you take your chances of injury. But what’s your legal liability if others come over to jump?

When someone sues a trampoline owner for injuries sustained, the owner will be judged on the precautions he took to prevent injuries. So leaving a trampoline on your yard when you know neighborhood kids will jump on it may not be considered reasonable cautious. But precautions like keeping a safety net around the trampoline in a fenced-in yard and warning those who jump – and their parents – of the risk of injury, not only prevents successful lawsuits but actually prevents injury.
