Rod Stewart used to put dog poo on his kids' pillows.
The Maggie May hitmaker - who has eight children from various relationships - always wanted to be a "friend" to his offspring, but was never afraid to use unusual methods to teach them a lesson when they were growing up.
His daughter Kimberly - whose mother is his ex-wife Alana Hamilton - said: "My dad was always our friend. He was still a dad in that he'd teach us lessons - if one of our dogs pooped on his nice carpets, he'd put the poop on our pillow at night - but we always wanted to tell him things.
"He never made us feel like we were being judged for what we did, probably because he had done everything that we were doing, times 1,000."
And the fun-loving rocker likes to prank his family's guests by pretending to be a parking enforcement officer.
