That was a mental picture, reading about the gusher after you ran over a sprinkler head! My DH won't even let me near the lawnmower -- the one time he tried to teach me how to use it, it was going so fast I was running after it holding onto the handle (I'm short). The darn thing almost climbed the fence as it's self propelled. Our neighbor nearly bust a gut laughing at the entertainment I was providing them. DH kept yelling "let go of it" but I couldn't hear him over the mower noise....
