"The House That Fred Built" is the second episode of the sixth season and the one hundred and forty-second overall episode of the original series, The Flintstones. It aired on September 24, 1965.


Wilma receives a letter from her mother, stating that she's coming to live with them, but Fred immediately tries to find her a home to move into, away from him.


News of Wilma's mother coming to Bedrock in rather a permanent way has Fred desperate to find a home for his foul-tempered mother-in-law, as far from him as possible. While en route with Barney to Bedrock's golf course, Fred discovers an unkempt but adaptable house for sale and "bargains" with the real estate agent responsible for the site so that Fred buys building and property for $100, which includes water right purchase.

Fred expects to have no difficulty at renovating the dilapidated domicile, but the hired carpenter and plumber, both unionized and non-working at a $20-per-hour rate, unjustifiably ascend Fred's expense account. So, Fred and Barney themselves toil in improvements to the house. Wilma and Betty assume the worst (i.e. infidelity) when their mates constantly leave home to secretly labor on the problematic abode.

After their wives follow them to the site, Fred and Barney have no choice but to tell about Fred's plan to accommodate Wilma's mother in the rendered-presentable house. Wilma and Betty assist in the task. No sooner is the work completed then the artesian well on top of which the house is situated deluges it with water.

The house must be transported to a better location, and while in the act of wheeling it to the Flintstones' yard, Fred and Barney lose control of the structure, which tumbles down a ravine. Fred is in tears when he calculates his sum loss in Operation Mother-in-Law's House to be $1000- and Wilma's mother decides not to reside with the Flintstones after all!
