Interesting coincidence that two of my top three webcomics use Matry(i)oshka *something* within about a week of each other. Erfworld just used a matryoshka doll as a plot device to facilitate an escape. I'll go with a coincidence for now, but if Order of the Stick updates with something similar, I will suspect either Russian interference or webcomic writers are or are becoming a hive mind.
Just saying, if you can somehow get nesting dolls into the next update, it would be a threesome :-)
