That's pretty astounding, regardless! I never would have guessed
such rapid dispersal.

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 pretty late.
