I have a fake.

Alison has had a cold the last two days and every time she coughs we tell her to take a drink of water. Well last night we got them McDonald's for dinner and with it they got milk. While daddy was getting gas in the car Porter and I have the following conversation.

Porter: "Mom I have a fake."
Me: "A fake what?"
Porter: (irritated) "A Fake, you know a fake."
Me: "No Porter I don't know what a fake is."
Porter: "cough cough, You know mom a fake cough."
Me: "O you do?"
Porter: "Yes mom and when I'm done with my fake I'll get a drink of milk."
Me: "Okay you do that."
Porter: (all excited) "Mom my fake is gone!"

What will he come up with next?
