Richard Posner's avatar recently gave a lecture in Second Life. New World Notes provides a transcript. Among my favorite parts:

Suddenly, a large wooden cube materializes in the middle of the auditorium, blocking Judge Posner from the audience-- an apparent griefer attack on the event, or the Judge himself.

[Posner]: That's an example of the kind of threat that worries me-- a huge box marching through an amphitheatre.

The audience laughs while chaos ensues, during which Hamlet Au briefly crashes out of the world, and the Judge notices an audience member:

JRP: Is that a raccoon?

Kear Nevzerov: I'm a "furry". Not sure how I got this way.

[Posner]: I think it's Al Qaeda.

KN: I'm really an IP lawyer from DC. Honest.

[Posner]: I like your tail.
