(this actually happened last week)
"I have a baby in my tummy!" Suzy says.
"Me too!" Says Sue.
Suzy then walks over to one of the other teachers, lifts her shirt, "grabs" at her stomach and hands an invisible something to her.
"Here you go. You can you hold my baby, Billy, okay?"
Then Sue proceeds to go to the window sill and lay in it, putting her knees up.
"Are you feeling sleepy, Sue?" I ask.
"Nope. I'm just laying down to get the baby out." She says plainly.
Well, of course!
