Professor Bainbridge directs our attention to the L.A. Times article "'Star Trek' Bit Players Cling On" (about StarTrek conventions) and intones: "What a way to make a living. I'm not quite sure for whom I feel sorrier: The has beens who make their living this way or the crazies who pay them."
That's nice. Except Michael Dante is Maab. Maab! From Friday's Child! And, even though the episode originally aired in 1967, it's since aired in almost every year since up to and including 2005.
On the other hand, I'd trade a hundred photo ops with Michael Dante for one with Roxann Dawson.
