The Marine World hermit crabs get festive:
In vertebrate news, I co-won the "Best Teacher Costume" prize by going as Justin.
I'm the one on the left. Yes, I know, that sounds like a joke, but I had one student who saw me at a distance before seeing me closer up later on. The realization that the guy by the water cooler was actually his female history teacher totally shattered his mind.
Edited to add: bonus picture of my win. On the right is coworker Wendy, who went as gum stuck to the bottom of a shoe.
I was rather proud of my man-posing on the catwalk, until I heard that secondary head Katherine remarked, "I've never seen Justin walk like that." Give me a break! It's awfully hard to walk like Justin when your knees are intact!
