Apparently, Elmo had a runny nose. And he's got a little nose, so it only takes a tiny bit of tissue, as you can see.
Molly takes GOOD care of Elmo! But...where did that tissue come from?
Hmmm, that couldn't have gotten there all by itself!
Everybody knows - tissue comes from...
...Mommy's bathroom! (It was all Elmo's idea!)
