Our liar had a neighbor who was elderly, when our liar was about 50, and when the elderly lady's husband died, she claimed to be taking over a casserole, being neighborly, to the woman. Upon knocking on the door, there was no answer. She took it upon herself to enter the kitchen to leave the casserole when she CLAIMS that she saw the woman in another room having oral sex performed on her by her dog. The liar took the casserole back home supposedly because she didn't want to embarrass the woman by having the woman realize that someone had been in the house during the sex act; however, she wasn't too embarrassed to tell her husband and a few friends to get the story snowballing.
She was wise enough not to ever name a specific time for this incident because the victim had security cameras running 24 hours a day, which was well known as she was upper-middle class to wealthy, a former town official, and her first husband was a prominent executive in the area until he died. Obviously no casserole could be left because that would pinpoint the date of the supposed event.
A small contingent of people mocked the victim, who was unwitting, and asked her about her lap-dog. She was such a nice woman that she just thought that people loved her dog as much as she did (but not like the liar claimed.)
