Yankel is making a bar mitzvah for his son and sends an invitation to his friend Moshe, who is a doctor.
COmes four days before the bar mitzvah hand Moshe realizes taht he has to send a response. Since he was in his office , ,he scribblred his respocse on on eof his prescription pads and sent the response to Yankel.
Yankel gets the reply but cannot read what Moshe’s response. You know about doctor’s handwriting.
Yankel is too embarrased to call Moshe to say he can’t read the reply.
He has a brilliant idea, he will go to the pharmacist, they seem to always be able to read doctor’s scribbles.
Pleased with hmself, Yankel goes to his corner drug store walks up to the counter and hands the pharamcist the paper.
He stands there waiting eagerly for the answer.
The pharmacist takes a look at the paper and says ” ok, come back an pick it up in half an hour”.
