The Fox Network's web page for Kelsey Grammer's sitcom Back to You
includes an apology for an "insensitive line of dialogue". The apology
reads:
""The Fox Broadcasting Company and 20th Century Fox Television wish to
offer a deep and sincere apology for the insensitive line of dialogue
during the November 14 episode of the comedy series 'Back to You. In
no way was this dialogue meant to insinuate any connection between the
Polish people and the Nazi movement. The line was delivered by a
character known for being ignorant, clueless, and for saying
outlandish things. Allowing the line to remain in the show, however,
demonstrated poor judgment and we apologize to anyone who was
offended. We have removed the line from the episode for all
distribution platforms and all future airings."
I can't ever imagine that happening on Frasier.
