3:44pm–#Fairfield CT– A school bus driver joking with the students had all the kids on board laughing except for one girl who did not know the bus driver was kidding around.  The bus driver joked he was tired and play acted as if he was sleepy and yawning, all the kids laughed but one who called her mother and said the bus driver might be drunk or having a medical emergency while traveling down Reef Road.  She gave a landmark of the Seagrape.  Lieutenant Keith Broderick told me officers on patrol observed the bus and found nothing out of the ordinary and followed the bus, stopping it in the 1000 block of Fairfield Beach Road.  Field sobriety tests found the driver sober.  Interviews with the students indicated that they knew he was joking around.    Officials from First Student and the Board of Education also went to the scene.  The bus is thought to be from Sherman School of 250 Fern Street.
