I suspect it's some kind of a joke, but I am not sure of its meaning.
Context: US movie 1949. This is the dialogue excerpt:
Potential buyer: Why is it for sale? (NOTE It=A farm with lemon groves)
Old and unkempt real state agent: Well, Mrs. Webb. She's the owner now, of course. She took her husband's accident pretty hard. They put her in the sanitarium. My instructions were to sell the place. So you don't have to worry about it being a lemon.
Potential buyer: I'm sure of that.
"lemon", besides being the name of a citrus fruit, is slang for something that is unsatisfactory or defective, especially something that you buy. So the joke is saying that it isn't a lemon (one meaning) when in fact it consists almost entirely of lemons (the other meaning). CJ
