Harry Melling: Dudley Dursley
Dudley Dursley : Daddy's gone mad hasn't he?
Harry : [writing HAPPY BIRTHDAY HARRY on the sand-like floor of the boat he and the Dursley's are in] Make a wish, Harry.
[looks at Dudley's watch, it is now his birthday, and blows on the dusty, sand-like floor, when someone is trying to break in, which wakes Dudley up]
Uncle Vernon : [come's into Dudley and Harry's room with a rifle and Aunt Petunia] Who's there?
[the door breaks open, and everyone screams in terror]
Hagrid : Sorry about that.
[puts door back on]
Uncle Vernon : I demand that you leave at once! You are breaking an entry!
Hagrid : [walks over to Vernon] Dry up, Dursley, you great prune!
[bends the rifle's end up and Vernon shoots and walks over to Dudley]
Hagrid : Boy, I hasn't seen yeh since you was a baby, Harry, but you're a little bit longer that I expected, especially right in the middle.
Dudley Dursley : I-I'm not Harry.
Harry : [walks over to Hagrid] I am.
Hagrid : Well, of course you are. Got somethin' for yeh, 'fraid I may have sat on it at some point, but I imagine it'll taste just the same.
[gives Harry a box]
Hagrid : Painted it myself, words and all.
[Dudley looks jealous]
Harry : [opens the box, to reveal a cake that says HAPPEE BIRTHDAE HARRY on it] Thank you.
Hagrid : It's not every day your young man turns eleven, eh?
