I got fired for telling a joke at an after Christmas party - party. I was retiring in 6 months so it worked out okay, got unemployment for the last 6 months I was to work.
BTW, Uncle Marty’s jokes sometimes frightened people. One such person was another Uncle from my mother’s side of the family. We invited that Uncle to go fishing with us (including Uncle Marty) but he vigorously declined. He didn’t
say why but we knew that he couldn’t abide by Uncle Marty’s jokes which included x-rated humor.
