I used to work part-time at UPS. One day, a box breaks open and it's full of belts. One of the women(black) grabs one, makes a spanking motion, then says she's going to use it one me. I replied something like "I knew you were a freak. You probably have all kinds of whips and whatnot at home." This type of talk went on for about 2 weeks.
Then one day, another lady I knew comes up to me and says she was with the employee retention committee. She goes on to say the woman was talking about filing a sexual harassment complaint against me. I told the lady that we had been joking for the past 2 weeks and that the woman initiated the conversation. I then go to the woman and ask, "why didn't you tell me we weren't joking anymore? I would've stopped." She says "I didn't know how to tell you."....But you are comfortable getting me fired?

It never went beyond that.
