Growing up, we had a separate home phone line that was listed in the phonebook and had a distinctive ring. So we knew when someone was calling us who had gotten our number out of the phonebook. This was most often telemarketers. So we would answer the phone and try to order a pizza from them, or pretend we only spoke pig-latin.

Is there anything inappropriate (Halachically/ethically) about doing that?

  • Personally, I like your sense of humour, and my friends and I have a list of prank calls we used to do to information operators (Gee, am I dating myself, here, or what??) that would have you rolling on the floor. (E.g. - we asked the operator "Where are my socks?") But there may be 2 problems - gneivat da'at and, perhaps, excessive levity?

  • @YEZ - I guess you haven't earned enough points to create new tags?

  • @DanF I try not to create new tags unless they seem necessary. Are there so many geneivas daas questions? Commented Jul 4, 2014 at 18:17

There is a prohibition of "Ona'at Devarim" - "Verbal Oppresion". This prohibition emanates from two closely placed verses - Vayikra 25:14 and 25:17 that state "Do not aggrieve one another." This article details the applications of "Ona'as Devarim".

In summary, the caller expected to make a sale. Your attempting to play jokes on him most likely aggrieved him and, perhaps, emabrassed him, as well - a separate prohibition. I would assume that the prohibition of Ona'at Devarim applies to not aggrieving gentiles as well as Jews, but I'd have to check that.

So, while you may have had fun, the caller and God, most likely, may not have had had the same sense of humour...

  • @DoubleAA - What makes you feel that it wouldn't apply to non-Jews? Wouldn't "darkei Shalom" apply?

  • Darkei shalom might, but onaah doesn't. That's what I said above.

    In re-reading my answer, I am rethinking my assumption. Does a telemarjeter really hope to make a sale when he calls? Or does it not actually matter? I mean, he would like to make the sale, but is that an expectation at the time of the call? It's not quiet the same as when a customer walks into your clothing store, unless he says or indicates that he's there to browse.

See Shulchan Aruch CM 227:26 which says that there is no prohibition of Onaas Mamon (money) when done to a goy. This is because of the passuk לא תונו איש את אחיו - A goy is not Achiv.

Concerning Onaas Devarim the passuk says LO TONU ISH ES Amiso, which also excludes goyim.


See Yam Shel shlomo Baba Kama 10:20 that if a chilul Hashem will be caused it is forbidden.

The SMA in CM 348:2 explains the Rema and Rambam that even when there is no Aveira of Onaah, if it involves Genaivas daas it is still forbidden.
