Dr. Jacoby: inspired by Terence McKenna?

My wife and I have been working our way through the definitive gold box edition of Twin Peaks recently; she's never seen it, and as rabid a fan as I was when it first aired, I never made it to the end of season two. (As David Lynch remarks on the box, "I think this is a great definitive Twin Peaks Gold Set...") Tonight we were looking up one of the bit players on IMDB (turns out, the voiceover lady from Desperate Housewives was in a few eps), and I stumbled over into the IMDB trivia for the show, which includes this tidbit:

Dr. Jacoby [played by Russ Tamblyn] is based on the late ethnobotanist, Terrence McKenna [sic]. Their physical appearance is strikingly similar, their dress style is similar and they are both in the liberal arts professions. Dr. Jacoby holidays in Hawaii and has a Hawaiian wife, McKenna lived in Hawaii. Dr. Jacoby has a notable mushroom shaped lamp, McKenna studied and wrote widely on psychedelic mushroom culture.

Ha! I usually assume a significant amount of bad data in IMDB's supporting info, but this was pretty hilarious, especially considering Dr. Jacoby's reduction to essentially a comic relief role in season two of the show. Of course, season two is where the show went off the tracks, but I guess that's a different discussion...
