Halloween is the best!
Why? Because it's one of the few times of the year I see some of the shortest Darth Vaders all on one day.

This year, both my nephews dressed as Vader.
(with sabers from yours truly).

And I wondered how many kids dressed as Vader this year, so doing a simple "tag" search on Flickr.com for the words "Vader Halloween," I found these gems.

Kids as Vader:
Epic battle on Washington road
Hey Superman -- Halloween
Batman and Vader in front of the fireplace
Vader at the Horribles Parade
Darth Kiran
Before... and after.
Vader in the backyard!
"I'm the real one, no, I am the real one ! No..."
Vader at the Haunted Halloween Zoo

Darth Doggies:
Darth Max!
Happy Sith Family...
Bark Vader

And this photo of a young Princess Leia with bagels as hairbuns was cute too...
