Say WHAT?

Some days Talan asks to go down for a nap.  Other days, like today, it's nearly impossible to get him to go to sleep.  It's not unusual for him to talk to himself which is what he did for at least an hour today.  About 45 minutes in, I went upstairs and put my ear to the door to listen in.  I was shocked at what I heard.  It went a little like this:

"Hi Sexy, come over here and look at this.  Okay Dappy, I'm coming over right now to look.  Sexy, did you see where Dalma went?  No.  Okay.  Let's get Dalma and Dappy and tell them to come play at Sexy's house."

Uh, come again?  What the heck?  So into his room I went to ask him what he was talking about.  When I walked in I noticed that he was in bed with a book in hand.  It was Scooby.  I told him to tell me the story and when he did I was relieved to know that Sexy was actually Shaggy, Dappy was Daphnie, and Dalma was Velma.  Innocent mistake.  I was happy to keep him up for another 15 minutes, reading the story, and making sure to say each name with exaggeration in hopes that he'll catch on.
