He must have watched the “LSD” Dragnet episode
Sensational headline notwithstanding, I’m sure the pot wasn’t the main reason this scumbag put the baby in the oven.
The episode you may be referring to is from the second season of the 1960s ‘Dragnet.’ It’s called ‘The Big High’ and features a young couple that routinely gets high on marijuana, but at the end their baby daughter drowns in a tub because they were too high to appreciate what was going on.
The LSD episode everyone remembers is the first regular episode of the first season.
In ‘The Big High’s’ epilogue, the mother of the child isn’t sent to prison, but rather is sent to a mental hospital.
In Webb We Trust!
That was a great episode!
