Bsd lol.
This thread is something anyone who speaks ivrit and learned in a Yeshiva is Israel should have several episodes to add here.
This one I witnessed. We were once in a pizza store when a group of American tourist invaded loudly, deciding what to order. They decided on pizza with mushrooms. Then one of them announced that as he spoke the language he would order. He went over and said “er, anee rowtze, er, pizza gadol im mitriot”! (mushrooms are pitriot, while mitriot are umbrellas!)
Another story goes that a guy needed to know the time. He asked someone “slicha, mah hashaah achshav”. They said “ein li musag”. So he asked somebody else. They replied “slicha ein li musag. So he went upto a 3rd guy and asked him “yesh lecha musag?” !!!
To change language, a chassidisher meshulach knocked on a house and the mother told the kid to say the father wasnt at home. The kid proudly said “mein tatte is nisht in zein hoizen”
