The Weird World of LSD (1967)

The 60s equivalent of Reefer Madness and all those other 30s drug exploitation flicks. Apparently, dropping acid leads to stripteases, cat fights, promiscuous sex, playing with kittens, and being convinced your dinner is much larger than it actually is. This is all illustrated in a series of silent sketches accompanied by a droll narrator who seems positively doped out of his mind.
