Wow, This Thing Is Going To Give Me Nightmares:

Reports the Post: "Toy peddlers are laughing all the way to the bank with Heath Ledger's Joker doll selling out at New York stores. Droves of people lined up early at the Toys 'R' Us store in Times Square... 'There are none left in the warehouse, either.'"

The dolls are retailing for $10 each, but are now up on EBay for $55! I doubt this thing would have sold as well if Heath had not died right before they began promoting the movie.
