The wonderful comic, Sam Levinson, had a great answer 
to anti-Semites.

"It's a free world and you don't have to like Jews,

but if you DON'T, I suggest that you boycott certain 
Jewish products, like.....

The Wasserman Test for syphilis,

Digitalis, discovered by Doctor Nuslin,

Insulin, discovered by Doctor Minofsky,

Chloral Hydrate, discovered by Doctor Lifreich,

The Schick Test for Diphtheria,

Vitamins, discovered by Doctor Funk,

Streptomycin, discovered by Doctor Woronan,

The Polio Pill by Doctor Sabin, and the 
Polio Vaccine by Doctor Jonas Salk.

Go on, boycott!

Humanitarian consistency requires that my people 
offer all these gifts to all people of the world.

Fanatic consistency requires that all bigots accept:

Syphilis,

Diabetes,

Convulsions,

Malnutrition,

Polio and Tuberculosis as a matter of principal.

You want to be mad at us? Be mad at us!

But I'm telling you, you ain't going to feel so good!
