A UPS driver in Temecula, California, has gone viral for his hilarious reaction after ringing a doorbell and spotting a 'baby sleeping' sign. Doorbell footage shows him take one look at the warning before making a remarkably quick exit from the porch. The baby's mother said she and her husband 'laughed so hard' when they watched the footage, explaining that the sign is there to prevent their barking dog from waking their child. #viral #california #doorcam #delivery
