(American folk song, origin unknown) A dialog between Henry and Liza over a chore with never‐ending quandaries!
Henry	Liza
There's a hole in my bucket! Dear Liza, Dear Liza. There's a hole in my bucket, Dear Liza, A hole!	Well, mend it! Dear Henry, Dear Henry, Dear Henry. Well, mend it! Dear Henry, Dear Henry, Mend it!
With what shall I mend it? Dear Liza, Dear Liza. With what shall I mend it? Dear Liza, With what?	With a straw! Dear Henry, Dear Henry, Dear Henry. With a straw! Dear Henry, Dear Henry, A straw!
But the straw is too long! Dear Liza, Dear Liza. But the straw is too long! Dear Liza, Too long!	Then cut it! Dear Henry, Dear Henry, Dear Henry. Then cut it! Dear Henry, Dear Henry, Cut it!
With what shall I cut it? Dear Liza, Dear Liza. With what shall I cut it? Dear Liza, Cut it?	With a knife! Dear Henry, Dear Henry, Dear Henry. With a knife! Dear Henry, Dear Henry, A knife!
But the knife is too dull! Dear Liza, Dear Liza. But the knife is too dull! Dear Liza, Too dull!	Then whet it! Dear Henry, Dear Henry, Dear Henry. Then whet it! Dear Henry, Dear Henry, Whet it! (Whet means “to sharpen.”)
With what shall I whet it? Dear Liza, Dear Liza. With what shall I whet it? Dear Liza, With what?	With a stone! Dear Henry, Dear Henry, Dear Henry. With a stone! Dear Henry, Dear Henry, A stone!
But the stone is too dry! Dear Liza, Dear Liza. But the stone is too dry! Dear Liza, Too dry!	Then wet it! Dear Henry, Dear Henry, Dear Henry. Then wet it! Dear Henry, Dear Henry, Wet it!
With what shall I wet it? Dear Liza, Dear Liza. With what shall I wet it? Dear Liza, Wet it?	With water! Dear Henry, Dear Henry, Dear Henry. With water! Dear Henry, Dear Henry, Water!
With what shall I fetch it? Dear Liza, Dear Liza. With what shall I fetch it? Dear Liza, With what?	With a bucket! Dear Henry, Dear Henry, Dear Henry. With a bucket! Dear Henry, Dear Henry, A bucket!
There's a hole in my bucket!
Virginia Maier, of Pittsburgh, PA, gave me a tape of this song from her collection.
