A toddler thought he could make a noise like a horn by squeezing his tummy when his family played a cheeky joke on him.
Footage shows two-year-old Asa standing in a boat on Lake Hartwell, South Carolina, on July 4 while celebrating Independence Day.
Dressed in just a diaper, he presses his stomach - and every time he does so, a friend of the family honks the boat's horn.
