Having heard many such stories of children sticking things in their noses I almost started laughing and went to grab the camera. Michelle, a bit more level-headed, headed for the medicine cabinet to grab some tweezers and a flashlight.
As it turned out it wasn't a marble after all. He had stuck a little bead up there and Michelle was able to just sqeeze it out. The whole incident was resolved in about 3 minutes and Michelle and I just had to laugh.
