I've found this wonderful tactic that I can use when I don't want to do something.  It's called "delaying" and I've gotten pretty good at it.  Mom and Dad even think that I tailor my "delaying" to each of them by trying to do things that they consider "fun" or "cute" as a way to stay up longer, not take my nap, not clean up my toys, you know, anything that isn't fun.  Here's a snippet of an episode I pulled on Dad one night.  Enjoy!
