Dentist and little boy

A shy little 4-year-old boy went to the dentist for his first cleaning and check-up. The hygienist tried to strike up a conversation, but no response.

After the cleaning, the dentist was called in to do the final check. The dentist then tried to strike up a conversation with the boy. "How old are you?" the dentist asked.

No response

The dentist then asked, "Don't you know how old you are?"

Immediately, four fingers went up.

"Oh," replied the dentist, "and do you know how old that is?"

Four little fingers went up once again.

Continuing the effort to get a response, the dentist asked, "Can you talk?"

The solemn little patient looked at him and asked, "Can you count?"
