U-T San Diego says the 31-year-old man and a woman were picked up Sunday night in Chula Vista then fell asleep during a 20-minute ride to a home.
Police Lt. Phil Collum says when they arrived, the man got into an argument with the cabbie over the fare.
Collum says he went into the house and came out with a didgeridoo a long, wooden instrument from Australia.
Collum says the man threatened the driver with it. The cabbie drove off, but the man allegedly chased the cab and whacked it several times with the didgeridoo, denting the vehicle.
Arriving police arrested the man on suspicion of vandalism.
