This is most excellent! Just when I was getting bored, you fill the void. I did, however, remember two characters that should be included. Hopefully, I didn't just absent-mindedly skip over them!
First, I think if "Art Vandeley" is included, then you should include Kramer's recurring fictional alter-ego "Professor Van Nostram" (Or something close to that effect)
Secondly, I did not see Elaine's boy friend that shared the name of the serial killer. I believe his last name was "Rifken"
Again, if I had simply skipped over these entries, then pardon this post. And again, great job so far! -Ro.
