What was the meanest joke you've ever pulled on someone? Mine was on a bratty cousin more than fifty years ago. I was a senior in high school and taking a course in the Russian language. In March, we had to go back to Kansas from Seattle due to my paternal grandmother's death and I took my Russian dictionary back with me so I could halfway keep up on, my Russian. After getting through her funeral we spent some time with my mom's side of the family and we were all gathered around in my uncle's house. My bratty cousin Glen saw my dictionary and wanted to know how to call his brother an SOB. He found the words in the English to Russian part and asked me how to pronounce them. I told him what to say and how to pronounce the Cyrillic characters, so he goes up to Tim, his brother, and in front of everyone there told him what I said to say. Tim looked at him with a 'what the hell' look on his face and Glen told him that he had just called him an SOB in Russian. I said, "No, Glen; you just called yourself one." Everyone there just busted out laughing. I know, mean; just rotten to the core. How's about anyone else?
