I am known for my sometimes outrageous humor in the most unexpected situations. Our office is close quarters and it helps. We had an accountant working for us - new to the company - who came to work impeccably dressed in vested suits. One day on casual Friday he walked in in jeans and an Irish knit sweater. The jeans were carefully pressed with a knifelike crease. The sweater screamed GQ. I looked at him and commented jokingly "Gee you're dressed like a bum today." Everyone including him laughed. Even in jeans he looked like a fashion statement. That day he filed a harassment complaint against me for belittling his clothing. He didn't get that it was a compliment. I refused to apologize and never said a word other than business to him ever again. Then he complained that I was ignoring him. Go figure.
