A David joke

When David woke up yesterday morning and I went to get him out of his crib, he sneezed. I said, "God bless you."
David got a big smile on his face and then he sneezed again, this time on purpose.
I smiled and said, "That's a fake sneeze."
David grinned, "I fake sneeze."
And that's how I spent the first ten minutes of my morning. Listen to David say:
"Achoo."
"I fake sneeze."
Over and over with the biggest smile on his face.
