While on my way to 18th century France, my TARDIS's nanophotogyrometer went on the blink and I ended up landing in 21st century Illinois. Well, while I was there, I decided I'd like to visit Midwest FurFest. Such a lovely convention! I haven't seen that sort of gathering of species since that one cantina on Gammarey IX (or was it IV?)
Apparently, I loved it so much that I decided to come back later, because I ended up crossing my own timestream and met myself from the future! What a nice fellow!
