Debbie Jellinsky from Addams Family Values, who earned the nickname "Black Widow" for murdering husbands who were too busy to give her the love she needed (it doesn't help that she, being a materialistic woman, likes to marry men who have a lot of money, who usually have to work around the clock).
Debbie : Sorry, Debbie, no Mercedes this year. We have to set an example. Oh yeah? Set this!
