Even the show House M.D. joked about this in the season 5 episode, The Social Contract.
Dr. House:"First of all, Wilson played tennis on his college team, and you...are a Jew." He tells Taub he's not athletic. Taub points out Sandy Koufax was Jewish, and House pooh-poohs him, saying that Jews always go on about Sandy Koufax, and the Holocaust. "It gets old."
Well, this book proves that Sandy Koufax is not the only Jew in sports, and actually has many quite exhaustive biographies on many Jewish sports legends. A very nice book in good shape, and thicker that the leaflet offered to Ann Nelson on the plane.
