Expertise:  I can answer questions about the television series, such as plotlines, guest stars, when the show(s) aired, what song(s) were performed, etc. In most cases I can even tell you which show used a certain line or contained a certain scene, although some of the more trivial questions may require some research on my part.

Experience in the area
I am a first generation fan, having originally watched the programs on NBC in 1966. I have all episodes on DVD and several reference books that add to the knowledge.
