If trees could scream, would we be so cavalier about cutting them down? We might, if they screamed all the time, for no good reason. Before you criticize someone, walk a mile in their shoes. That way, you'll be a mile away from them, and you'll have their shoes.
It's funny you said that as I had considered posting that same one and decided against it for the same reason. I imagined I'd get hateful messages from people thinking me monstrous to find the torment of a child amusing. But come on, it kind of is - at least how Jack Handy presents it :)
I liked this one, but I think a lot of people may not know the source, and would think it is meant to be taken seriously. 'One thing kids like is to be tricked. For instance, I was going to take my little nephew to Disneyland, but instead I drove him to an old burned-out warehouse. "Oh, no," I said, "Disneyland burned down." He cried and cried, but I think that, deep down, he thought it was a pretty good joke. I started to drive over to the real Disneyland, but it was getting late.'
