Three very familiar faces from classic-era TV and/or movies guest starred in this episode: Richard Deacon, Pat Harrington Jr., and Jane Withers.
The title to this episode refers to Deacon's character, "Borden T. Pike," who is manager of the city gas company which is determined to run a pipeline through the neighborhood, which includes underneath the Munsters house. Withers plays "Fanny," Deacon's jealous wife.
After frazzled employees come back to Deacon's office explaining they saw monsters, while accidentally digging into the Munsters basement, Pike goes to look for himself, determined not to be taken in. Thus, when he sees the Munster family he figures it's all a ruse so he's not scared or intimidated.....until Grandpa turn into a bat. Then Pike splits, in a hurry.
The next scenes are the best as Pike has his insanely jealous wife meet a couple of the Munsters and Grandpa gives the utility guy a hard time. There are some very funny lines in here, such as near the end when Pike's boss tell him, "Men like you give gas a bad name!"
In the end, pun intended, things work out to everyone's satisfaction, including Pike's marriage. "After meeting you," Pike writes to Herman, "my wife and I have never looked so good to each other."
