This birthday party took place on 23 June, 1990 to celebrate Dudley Dursley's tenth birthday. The entertainment was unintentionally provided by Harry Potter when he accidentally stepped on Ripper the bulldog, therefore provoking the enraged mutt into chasing him out into the garden and up a tree. Dudley and his parents got laugh out of this, until his Aunt Marge finally agreed to call her dog off sometime past midnight.[1]
