In 1997, my soon to be Daughter-In-Law, visited the missus and I for the first time. She began ranting about guns, politics and etc. ad naseaum. I (calmly I might add) opened the front door, looked at her and said; "Listen you psycho bitch, this is my house, if you don't like what you see here get the f..k out, and don't waste any time doing it. Open your pie hole one more time, and I'll personally throw your fat lazy ass out myself."
Son and missus were appalled. DIL respects me. Won't come to visit though.
