Quote from : Harry Potter and the Sorcerer's Stone Movie

Dudley Dursley: [on Dudley's birthday] How many are there?
Uncle Vernon: 36, counted them myself.
Dudley Dursley: 36! But last year, last year I had 37!
Uncle Vernon: Yes, yes, but some of them are quite a bit bigger than last year.
Dudley Dursley: I don't care how big they are!
