Leeneia:
you are thinking of Lewis Carroll's immortal DORMOUSE,
who was always going on about treacle.
This was at the dinner party
attended by Alice in Wonderland,
with the insecure and defensive Mad Hatter,
speaking up for the Dormouse:

"You can draw water out of a water well,
so you ought to draw treacle out of a treacle well,
eh stupid?"

Which reminds me of a moment later in the book,
where the Red Queen is trying to outtalk everyone else,
and is interrupted by a sleepy voice which drawls,
"TREACLE."

And the Red Queen loses it:
"Behead that Dormouse!!"
