Jack Be Fruitful. Doth He Multiply?

Do they write? Do they call? A father's day card?

Apparently not, for the most part. Of the 9000 potential offspring 70-year-old Jack Nicholson does not claim, only Jennifer Nicholson with ex-wife Sandra Knight, Caleb Goddard with Susan Anspach and Lorraine and Raymond Nicholson with (more or less current gal pal) Rebecca Broussard acknowledge their parentage.

Intriguingly, acknowledging his own father is something Nicholson will not do.
