Normally you brush your teeth after you've eaten fish, but it seems one trout decided to eat a toothbrush instead.
A late-evening snag on Lake Tikitapu (Blue Lake) in Rotorua landed keen fisherman Alfred Hoyle a 2kg rainbow trout recently, and while gutting it, he felt a "particularly hard lump" in the stomach of the fish. He slit it open - only for the head of a toothbrush to pop out.
Amused at first, Hoyle said it was the reality of such a popular lake, and that campervan users may be the culprits.
"They come and brush their teeth and get water from the lake," he said.
