Clayton Littlejohn (King's College, London) wins the prize for it. He posted the following earlier today:
After considerable deliberation and reflection I've decided that it's time to go to Oxford. It wasn't an easy decision. I love London and will miss all the wonderful people I've met here.
This post was liked by more than 250 people, and elicited hundreds of congratulations (even after my warning that it might be a joke). After many hours, we learned that Dr. Littlejohn had gone to Oxford for the day to sell some rare books:
UPDATE: lovely time at Blackwells. Sold 6 books! Now I'm heading back to London (and KCL where I plan to stay for a very long time-unless they murder me).
Still to be determined: how many folks will unfriend Clayton on FB!
