What a crappy way to treat your dad.
Dwayne "The Rock" Johnson has posted a photo of the exact moment his eight-month-old daughter pooped on him.
The 44-year-old movie star told his Instagram fans that the messy mishap took place on Monday.
"In the spirit of Labour Day, I had an amazing philosophical conversation [with] my baby girl about the value of hard work and how respect is given when it's earned," he wrote in the caption.
"I told her, 'Baby girl when you grow up, you get out there and dent the universe through hard work and sweat. And always make sure you do it in a positive way with class, dignity and respect.'
"She responded by pooing on me in this moment as she plays her favourite game, 'Drum time on daddy's big head'. It was a good talk."
Johnson's daughter, Jasmine, was born in December last year.
She is Johnson's first child with his long-time girlfriend, Lauren Hashian, who he met when filming The Game Plan in 2006.
