I never would have figured it out on my own!!
I only got it cuz of D Friedlander's hint, though I actually prefer NCIS, whose characters have respect for the dead, over CSI, which has a nickname for them. Or something.
Hee hee, Gothick. "Not gumming" refers to Frid still having his teeth. It's just an awfully awful title to an ageist piece.
