Daws Butler, the voice of the cop, replaced Mel Blanc for several episodes in Season 2 after Blanc was involved in an accident which almost cost him his life.
ABC originally broadcast this episode in black and white.
The scene where Barney has a mishap with a harpoon gun is a shot-by-shot remake of the unaired pilot The Flagstones (1960).
Many elements of this story were reused in the later Hanna Barbera animated sitcom "Wait Till Your Father Gets Home."
