All havoc breaks loose when Shirley buys a cockoo clock for $29 at Bartlet's Department store. It seems Bartlet's has recently installed a computer to handle all their accounts. When Shirley receives her computerized bill for the clock, it reads $290 instead of $29. She goes down to the store to straighten things out with Mr. Atwater. Atwater apologizes and instructs the computer operator, Tom, to program the 1984-Z to move the decimal point and correct the bill to read $29. (Tom is quite impressed with Laurie). The decimal point is moved – the wrong way! Shirley's bill is now $2,900. The computer has sent bad-risk notices to other companies, ruining the Partridge's credit rating. It has also had a collection agency pick up the check from the family's last engagement. Shirley again goes go Barlet's; things are quite out of hand. While she's seeing the manager, Laurie leads a picket line outside the store. When they arrive home, the collection agency has repossessed all their furniture. (thetvdb.com)
