My wife and I didn't have time this year to plan a lot for Halloween, but I did go in to work as Indiana Jones. I already have the gear, so I just had to stop shaving for three days.
Then, tonight, I went to choir as "Super Jedi Indiana Jones." I had a big Superman muscle chest costume on under my Indy costume, and then I had a lightsaber. It was awesome, and so geeky!
