Don't sell bread to little Jewish boys

Odessa. An ordinary Jewish family. Little son returns from the shop without bread and with tears in his eyes, saying that owner of the shop told him that they "don't sell bread to little Jewish boys".
Of course, the father gets mad and rushes into the shop, shouting:
- Why haven’t you sold bread to my son?! This is Antisemitism!!
An old Jew, the owner of the shop, raises his eyebrows and says:
- What's with all the noise? Have you tasted this yesterday's bread?!!!
