My son went to the dentist yesterday.  He loves the dentist and having his teeth cleaned.  He was such a good patient.  He even sat through bite wing xrays.  Towards the end of his appt while the dentist was looking at his xrays, my son leaned on the arm of the chair and looked at the dentist and as serious as serious could be said "Are you sure you know what you are doing with that?"  Needless to say I was laughing very hard along with his assistant.
