When I used to watch Bevis & Butthead (OK, I still watch them), there was a character that Butthead created, "Cornholio". He would take his hands and, well, I'll let my boy show you:
Is this detrimental to his development? Is this possibly a blow to his general well-being? I don't know, but its fun to do stuff like this. At least I'm not giving him sips of beer or blowing smoke in his face or something.
I am so jealous of his hair. I don't have any (its all migrated to other areas, like my ears) and long for the days when I too, had long locks of hair. So when its bath time, sometimes I get to do stuff like this: The Soaphawk.
