Mrs. Goldberg went to the doctor because she hadnt been regular in quite some time. The doctor examined her, found nothing unusual and attributed her problem to her diet and her age. He recommended that she take a laxative.

Doctor, Mrs. Goldberg admonished him, remember – Im kosher. Whatever you prescribe for me MUST be kosher!

Mrs. Goldberg, he replied, I want you to take Serutan and dont worry, its kosher.

Youre sure, doctor? Youre absolutely positive its kosher? Because if its not kosher, I cant take it and Id be very upset to find out it wasnt kosher!

Mrs. Goldberg, the doctor assured her, of course its kosher. Serutan spelled backwards is NATURES and what could be more kosher than nature?

Reassured, Mrs. Goldberg left the office. Two weeks later, Mrs. Goldberg came storming into the doctors office. Doctor! she screamed, Im so angry at you! Im going to sue!

Whats wrong Mrs. Goldberg? Whats the matter? the doctor asked, very concerned.

That medicine you told me to take – its NOT kosher! replied Mrs. Goldberg. Of course its kosher Mrs. Goldberg, replied the doctor. Its called Serutan, and serutan spelled backwards is natures. What could be more kosher than nature? repeated the doctor.

Well doctor, Mrs. Goldberg answered indignantly, Serutan spelled backwards may be natures, but taking Serutan gave me such gas! And FART spelled backwards, is TRAF!

For the Yiddish-impaired, traf (pronounced trafe) means UN-KOSHER!
