This took me a few minutes before I LOLed but here's the communication between my sister and the planner of the b'nai mitzvah of my twin niece and nephew:
[Planner] We are delighted to have the opportunity of hosting the upcoming Bar Mitzvah …
[Sister] Can you please change the name of the event to B’nai Mitzvah?
[Planner] I hope you and your family had a Merry Christmas! I have put the request in to change the name to say B’nai Mitzvah.
