Bart the 90 Year Old Man Nearly Kills Me

Bart was a 90 year old man who lived on his own, and everyone loved him. His wife had died like 20 or 30 years ago; he now lives alone with the dog Rosie. Bart is so obsessed with Rosie that she has taken over his life. He tells sardid sex stories about what them and Rosie get up to until they quiz him. Then it becomes apparent Rosie's actually a dog - not a woman but a cock or spaniel called Rosie.
