Dudley Dursley's eleventh birthday

"Thirty-six. That's two less than last year!"

- Dudley's tantrum on his eleventh birthday

Dudley Dursley's eleventh birthday was celebrated on 23 June, 1991. He received 36 presents, including a new computer, a second television, a remote control aeroplane, sixteen new computer games, a gold wristwatch, a video recorder, a cine-camera, a remote control, a racing bicycle, (which Harry found odd, as Dudley was very fat and hated exercise if it did not include punching someone), and more. When Dudley counted his presents, he was mortified that he had two fewer than his last birthday: he became very angry at being corrected even though there was still one less present. Petunia promised that when the family went out to the zoo, she would buy him two more presents so he would have one more than last year.
