What the.....?!

I either should have paid more attention in my developmental psych class, or taken more of them, so I would know when to expect certain things to come out of my childrens' mouths and know when they can make certain connections.  We were sitting at the dinner table last night and I had forgotten to turn off the TV, which we usually do.  The nightly news was on, and a story came on about Glen Campbell, who was recently diagnosed with Alzheimer's disease.  The anchor was delivering the story and mentioned something about the fact that Glen had been noticing he had short term memory loss for awhile, but that the Alzheimer's diagnosis had been in the last six months. 

I kid you not - Carrie stops mid-chew and exclaims "Short term memory loss!!!  That's what Dory has in Finding Nemo!!" 

I texted Jerry to tell him what had just happened (he was at a business dinner...at Lady & Sons....which I have been begging to go to since we moved here.....but that's another story).  He called me back and thought I was making it up.  No, m'dear, not making it up.  Can't make this kind of stuff up!

Huh? 

How do they remember stuff like that?  Especially since I can't really remember the last time we watched that movie, as everything is all Princess, all the time right now.
