Was hosting a party at my place, and was planning to break up with my GF the next morning. While I was putting things away before guests showed up, an early arrival walked into the room and declared her interest in being the replacement by grabbing my shirt, letting me know one of my roommate had informed her of the plans, and locking lips with me.
When the about-to-be-ex walked in on me with the soon-to-be girlfriend with her tongue down my throat, the new flame did the dumping for me.
"Oh, hello, Sudsy's breaking up with you. Close the door, would you, love?" All I ended up seeing of the actual party was the cleanup in the morning....
Fond memories of that girl, sadly her visa expired and I didn't have the funds to follow her back to England. Then again, if I had had the funds, I likely would never have found my way to Japan.
