I guess I'll start. Have you heard the one about the baby in the oven?
There are many variations on this story, but this one first appears in the early seventies:
A couple hires a hippie baby-sitter who proceeds to get stoned on acid, marijuana, or sometimes even scotch. Later in the evening the mother calls up to see how things are going, and the baby-sitter says everything's fine, she just stuffed the turkey and put it in the oven. The mother hangs up, then suddenly thinks, "What turkey?" (The mothers in these stories are always incredibly stupid.) Both parents rush home and find the kid's been cooked, while the baby-sitter watches with a spaced-out smile. (In some versions the baby-sitter has set the table with crystal and candles and says, "Look, I fixed a special dinner for you.")
