re: #448 PT Barnum
The one I read in an Isaac Asimov humor collection (that guy wrote about everything):
Guy goes to his urologist, Dr. Finkelstein. And during the exam, the doctor says “You’re bris was done by Isaac Goldman, right?”
The patient says “How did you know?”
“He always cuts on the bias”, replies the doctor.
I’m not jewish just love jokes.
I own the book!
