For about the past month, my kids have been utterly obsessed with the Muppet Show. They are turning into miniature YouTube addicts. (In contrast to the rest of us, who are full-blown addicts by now.) This is the clip that started it all - their gateway drug, you might say. I have to admit it is very funny, especially the cows' mouths, even though I've now heard it, oh, a hundred times or so.
