Since I got this picture, I have wondered what is going on. Mostly, I make up conversations. I also wonder if Jeanette just told them their first dirty joke, something like, "What happens when you cross a pig and a clown? A DIRTY JOKE!"
It was probably something extra amazing, like Jeanette just lost the game of jacks and announced "KITTENS FOR EVERYONE!" to divert the attention from her sad loss.
