Long before Seth Rogen and James Franco were smoking pineapple express in, uh, Pineapple Express, Tommy Chong and Cheech Marin were the original stoner duo, mastering the pot-smoking comedy formula with "Cheech & Chong."

Well, reefer madness is officially back, and Tommy Chong has decided to capitalize on it yet again, with his new book, "Cheech & Chong: The Unauthorized Autobiography." The actor/ comedian/ musician/ writer will discuss and sign copies of the book tomorrow, Wednesday, August 12, from 12:30pm to 1:45pm at the Bryant Park Reading Room (located under the trees on the 42nd Street side of Bryant Park, between the back of the NYPL and 6th Avenue). The event is free and will be hosted by Josh Gilbert, director of the documentary film, "A/k/a Tommy Chong." If it rains, the alternate location is the Library of the General Society of Mechanics and Tradesmen at 20 West 44th Street (between 5th and 6th Avenues)--and yes, that does strike us a totally bizarre yet somehow totally appropriate locale.
