Nope, nope, nope. I am that grumpy person that wishes they'd stop wasting money and bright minds off planet when there is so much to be done with them on Earth.
My 3 year old and 1 year old definitely know better than this - I'd be surprised if they went that far because my reaction would definitely not be that calm, and they know it! Of course, that right there is breaking my rule that I don't promise what my kids will or will not do - it's just asking for it, really :).
