A high school science teacher named David Layman worked together with others via an unofficial Facebook Breaking Bad fan club to place an obituary on page A4 of the Albuquerque Journal for the chemistry teacher turned drug kingpin.

"Greatly missed"? Did these people even watch the show? The only thing that misses Walter White is the beige clothing industry.
