Stephan Pastis, author of the comic Pearls Before Swine, blogged about his recent experience on a plane: 
Flew back from Hollywood yesterday and wanted to let you know that if any of you are having trouble speaking today, I know why.

The woman sitting across from me on the plane used up all the words.
This is even funnier if you read the comic and know a little bit about the character of Rat.  Pastis recently said this:  "Rat's voice is effectively my voice.  If I could, I'd write for Rat every day." #psychology
