What Does It Mean?

[Marijn]

This "joke" was on my calendar, and I don't get it. . . . .

Last night we had three small zucchini for dinner that were grown within fifty feet of our back door. I estimate they cost somewhere in the neighbourhood of $371.49 each.
(Apparently it's a quote from Andy Rooney (whoever he is)).

I think -- think -- it's meant to be observational comedy. The expense of growing your own food.

The joke is obviously that the speaker is confusing average with marginal cost....

^sorry, that's as funny as economics gets.

I think that must be it, Jim. I just googled him and he's some man that used to be on the radio in America. He doesn't sound very funny to me. Thanks for your answer.

Sorry dr b, I don't understand your answer. Thank you for answering.

Wouldn't Andy Rooney have said "neighborhood" and not "neighbourhood"?

I wrote it without the "u", but spell checker Anglicized it.
