I dont know what kind of story this qualifies as but anyway,
A rav (possibly R’ Aryeh Levin -maybe someone could confirm it) once went to a doctor with his wife, who hurt her foot. When the doctor asked what the trouble was he replied, “Doctor, my wifes foot is hurting us.”
I think this is the way this story goes:
A man walked into a store and saw the owner working and his two sons learning with much enthusiasm. he asked the owner why he was zoche to sons like that and he answered with a story. he was known as a popular philanthropist and many years earlier he went to a certain rav and said he would like to do something to merit sons who would learn torah. the rav told him there were two boys, both learning in a local yeshiva who had “outgrown” the learning at a very young age and needed to be sent somewhere else. unfortunately due to lack of funding they were unable to go, but if this philanthropist would put up the money then he would merit sons as he wanted. the man put up the money and his sons were learning torah, just as he wanted. the listener asked who the boys who received the money were. oh it was, (R’)Moshe Feinstein and (R’)Ahron Kotler (I have also heard a variation with R’ Yaakov Kamanetzky)
