"I lost it in my mouth"

On Christmas Eve, we went out for a drive to look at Christmas lights.  Mabel was busy playing with a small blue pebble a little bigger than a dime.  Suddenly she yells out, "I lost it in my mouth."  When we realized what she had lost, we all started laughing because she had swallowed her pebble.  She kept insisting that we try to find it, but nobody was willing.  If you ask her today, she'll tell you that "There was a rock in my butt crack."

P.S. Let the record show that the pebble in the above picture is NOT the same pebble that Mabel swallowed.
