7 - 21: Gumby with a Pokey

Charlie finds himself with insomnia, and is given prescription marijuana by his pharmacist (Martin Mull) to help him sleep. After smoking it with Berta, Charlie has disturbing visions of women from his past; Alan and Jake drive to Sacramento to pick up a valuable antique grandfather clock left to Alan by Judith's recently deceased grandfather. While riding home in the car, the clock falls out of Alan's trunk and smashes in to pieces, making his and Jake's trip futile. ZZ Top guest star as themselves. Title quotation from: Russell, Charlie's pharmacist, describing the effects of Viagra taken with a muscle relaxant.
