Zener diodes are some of the few devices you can series reliably. You may not be able to parallel them, but putting them in series will also raise their power handling ability. I.e. Two 8 volt 1/2 watt zeners in series will be a 16 volt 1 watt Zener.

I don't know about man.... If you have two zeners in series the current in each won't be half the total current then you will have total dissipation in each zener

Yea but you have half of the total voltage on each diode. If you have 1/2W 8V zenner you can put 63mA. If you series two 8V 1/2W zenners you stil can put 63mA but at 16V this give you 1W.
