He's talking about this old section on I-Mockery:
http://www.i-mockery.com/doctorbactine/
Dr. Bactine was something that Max Burbank and I created a while back. Basically, we would each take turns responding to the various emails that were sent in to us. Had a lot o' fun with it for a while, but eventually we just moved on to other things. Good to hear somebody still remembers that section of the site though!
