I love it also. My son loves to act out the scences from the cartoons. In Charlie Brown Christmas, remember the line,"Pantaphobia, the fear of everything." Charlie says, that's it! You have to love peanuts.
AM: Pentaphobia was one of DS's favorite scenes to reenact for a while, too.
I went through a period of worrying whether Charlie Brown is age appropriate for him (he went through a Calvin and Hobbes phase at age 5 that was murderous - we finally had to hide the books!), but then I realized that, if we read the books together, there is much rich material for chatting and thoughtful interaction.
At this time, DS is channeling Sally very usefully to help him cope with his entering first grade anxiety.
By the way, Val, I am Ian ('fitzi'). Your story is a classic.
