Scenen er Cannery Row i Monterey, Californien. Doc er gået i stå indehaveren af Vestkystens Biologiske Laboratorium er vendt rastløs og desillusioneret hjem fra 2. verdenskrig. Hans videnskab ligger stille, han gider knap nok se til sine blæksprutter og klapperslanger. Men så beslutter Docs venner at tage affære. Dagdriverne fra Ungkarlehjemmet "Palace" og pigerne fra byens ikke helt almindelige bordel "The Bear Flag" slår sig sammen og skaffer Doc det mikroskop, der bringer hans forskning videre og tilmed skaffer ham en ung og herlig kone. "En dejlig torsdag" er den uopslidelige historie om Doc, bordelmutter, købmanden og kumpanerne, der sværger til whiskymærket "Old Tennis Shoes".
