While I was in San Fransisco, John Scalzi and I headed over to Borderlands to do a reading. The day before we went, Scalzi suggested doing science-fiction improv, which sounded like a ridiculous amount of fun. Fortunately, John Nichols brought his digital recorder and captured the whole evening.
Scalzi, being the good guy that he is, edited the improv into a file for your enjoyment. So click on over to listen to PetMaster 2000.
