Joan was expecting a new car as a birthday present from her husband Bob, but by the end of the day she realized that he had forgotten her birthday. She left him a note the next morning saying, "When I get home from work today, I want to see something in the driveway that goes from 0 to 200 in 6 seconds!"

When she arrived home and looked in the driveway she found a bathroom scale.

Joan is currently listed by police as a "person of interest" in Bob's disappearance.
