Using the AVR internal temperature sensor

why not

void setup() {
  // set up the LCD's number of rows and columns: 
  lcd.begin(16, 2);
  analogReference(INTERNAL);
}

void loop() {
  // set the cursor to column 0, line 1
  // (note: line 1 is the second row, since counting begins with 0):
  lcd.setCursor(0, 1);
  lcd.print(analogRead(8));
}

now only thing i'm curious about is obtaining the Tos from the eeprom as mentioned in the manual. Which can be used as the offset for calibration.
