David's first name comes from the name of his voice actor David Boat. When he appears in custom neighborhoods, his personality, interests and skills will be different from the ones he has in Pleasantview, seen below.
David has the same facial structure as Komei Tellerman. He can easily be cloned in Create a Sim with debugging mode on. Often going unnoticed, David has 24 personality points instead of the usual 25.
Do NOT attempt to add David to a household, make him selectable, or tamper with him in any way or form. Doing so will corrupt the neighborhood he is in.
