The episode: “Beginning of the End,” ep. 517
The riff: Suggested by Crow while Peter Graves’ scientist character learns they need stronger weapons against the giant, invading grasshoppers in the movie.
The explanation: Okay, this one is pretty obscure. “Chlordane” is one of several names for a pesticide that was used in the U.S. from the 1940s to the 1980s, when it was banned by the EPA because of long-term danger to drinking water. “Retsyn,” on the other hand, is an ingredient that was long a central part of the marketing campaign for the breath-fresheners Certs. Note that I do not say “breath mints,” as Certs doesn’t actually have any mint in it. Retsyn, a mixture of “copper gluconate, hydrogenated cottonseed oil and ‘flavoring,'” is the source of both the “minty” flavors and green flecks in Certs. So really, Crow is suggesting a deadly poison with something to help it go down a little easier, as it were.
Novelty factor: I didn’t know about any of this, although “Retsyn” sounds vaguely familiar. I think the SOL crew may have made jokes about things “with Retysyn” before.
