I volunteered. I wanted to do some hands on stuff but I ran out of time so instead I stood by the soldering irons and made people sign liability waivers. I met a mom with 2 boys named Calvin and Hobbes and yes I asked her about that... another mom had some kids wearing Chewbacca backpacks and I told her I have the Yoda one and then I said I was late getting to the faire because I had been watching Star Wars Despecialized (the original with no extra crap) and she said she'd find it online. Another couple and I talked about our favorite episodes of Community, I can't remember how it started but we ended up cracking each other up trying to decide the funniest one. The flash back was a strong contender.
