Why is David's penis so short?

[curious george]

Dear Zambia,

Michelangelo's David in the Galleria dell'Accademia, Florence, Italy is considered a masterpiece for the ages. although people do not like to discuss the obvious. Why is David's penis so short and stubby? His testicles actually hangs lower than the penis.
Why?
