Fred asks Barney to help him build an extension to his home. However, their friendship soon becomes threatened.
Barney's decisive vote against Fred in the Water Buffalo of the Year campaign (after Fred's "may-the-best-man-win" dictate resulted in Barney selecting Joe Rockhead for the honorary title) results in a bitter squabble over a new room-adjunct to cave Flintstone built earlier in cooperation by Fred and Barney across the Flintstone-Rubble property line.
After penciling a division of the room in proportions dictated by Flintstone and Rubble yard ownership, Barney proceeds with his television at full volume to noisily disturb Fred's attempt at leisurely reading. Irritated and enraged by Barney's willfully disruptive conduct, Fred constructs a wooden fence over the room boundary, and hostility escalates rapidly. Bamm-Bamm resolves the conflict by dislodging a crucial beam from its foundation to cause the room of contention to collapse, and Fred and Barney reconcile, the initial reason for their feud forgotten.
