We did have two of everything for a while - matching D60s even! Once he started putting serious money into the stuff I couldn't compete. On the plus side, since he's having to buy new FX lenses for the D800, I get his hand-me-downs. Such a pretty wide angle...and the low light 35mm lens.... and there's always enough flashes to go around.
My favorite Christmas present last year? 55-300 lens
