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.
