This is way off topic, but did you ever notice that the characters on Sesame Street that date back to the 70's - Big Bird, Grover, Oscar the Grouch, Cookie Monster, The Count, etc. - are all adults while the more recent additions like Elmo, Rosita, Zoe and Baby Bear are all kids. I'm not sure what it means, but it made me think: Did the makers of the show decide they needed characters that kids could identify with better? Or did the original characters somehow grow up? That's a sorta wacky thought.
In case you're wondering, Patrick watches Sesame Steet every morning and I have to sit in with him to make sure he doesn't climb out of his high chair.
