David starts with 6 points in Guitar and 5 in Gardening. He does not know anyone outside of his home aside from his boss at the start of the game. He is also a 3-star celebrity if The Sims 3: Late Night is installed.
David Ziggfield is a reference to David Bowie, a well-known English musician. Ziggfield bears a striking resemblance to a slightly younger Bowie. Bowie also developed a well-known persona named Ziggy Stardust (likely the origin of the last name Ziggfield). David Ziggfield is also married to a woman who strongly resembles Bowie's wife Iman.
