My reference was when Thorn (C. Heston), as NY cop, was able to gain insight to those that had fresh fruit\vegetables and surmised they came from beyond. One gal left a strawberry clue and created quite a moral issue for Thorn. It is my understanding that there is a NY Soylent Green Biscuit Company. You never know.
I've never done LSD, but I imagine it's a lot like the last few posts in this thread. Obscure, interesting, and barely comprehensible.
