I was able to watch this episode this evening thanks to someone who was kind enough to tape it. (And FYI, to the person in question, you will be amply rewarded early next month.
)
Now, for worthless information about this particular Selby appearance that you can file under why/how he got the gig -- David played the father of Doug on the show, and Doug is played by Taylor Nichols. Taylor Nichols appeared with David in
Headless Body in Topless Bar, and that's supposedly why he was asked to do this quickie part.
This worthless piece of Selby trivia has been brought to you by Criseyde. (Ain't it amazing what I can spend my time on when I'm supposed to be grading papers?)
