Some moth-eared listeners caught me in a blooper at 45m05s in last Friday's Radio Derb podcast.

I said:

Let's flip the state ideology right round, into a configuration we have never tried before: Proposition R together with Proposition L, no negatives . . .

That should of course have been "Proposition Not-R together with Proposition L."  My apologies for the blunder.

Moral of the story:  Don't attempt manipulations in the Propositional Calculus while stoned on DayQuil.
