Our four year son has a gator electric car, bouncy house, bike, scooter, sandbox and kids pool in the yard and yesterday he asked for a trampoline. The answer was no. Would you like to know why?Frankly I'm scared he'll break his neck, or one of the neighborhood kids will. Although, trampolines do provide countless hours of backyard fun, but that they also provide some of the funniest human fails, as you can see in this compilation.
