KEN P.D. SNYDECAST #188: Die Abby has a moment where Ken admonishes Dana for using the term "gypped" and says it's a slur against Gypsies.
Is that true? Or is it an urban legend, like the belief that the term "rule of thumb" has etymological origins in a law that limited the maximum thickness of a stick with which it was permissible for a man to beat his wife. (It doesn't, btw.)
So, who better to turn to to find the origin of "gypped" than Popo's sister, Ann Landers!
The topic was discussed in a column from June 24, 1978.
