In any case, one of them, called "Your Eyes Are Sparkling Like Club Soda" (nice!), occasionally features some cool behind the scenes shots of the show being made. Uppermost you see Mike Farrell directing Season 7's "Ain't Love Grand?" and below that the cast shooting a scene from what I think is Season 8's "April Fools."
I love seeing shots like this, even if it does question my belief that the 4077th is real.
