Is She A Bad Mother?

So this Mom in Ohio played a prank on her two quite young kids.  She put a fake tongue on the floor and then held her mouth as if she couldn't talk.  Like her tongue got cut out  When the kids see the tongue on the floor, it scares the craps out of them and they take off running and crying...When they come back they're still crying and tell her to go to the doctor.  She kept the prank going for about 45 seconds. What a terrible Mom!!!!
