Lucy & Ricky's "Rent Strike"????
It was a "plot extender": Fred turns the gas off, and Ricky's shower gets Cold, too! (Cussin' in Spanish, well!!!! --LOL) I think the water gets shut off next...
So Lucy is unable to use her stove... (And didn't turning off the electricity make the TV screen go black?)
I view the likely event as Fred & Ethel's apartment complex getting a "trial use" of gas ranges & back then, someone actually willing to swap electric for gas, then the other way around, going through the trouble of taking out those 40" Westinghouse's for 40" Ropers, then vice-versa...!
(Frd can't see much of a difference in the way of gaining an increase in his tenants' utility bills, either way, huh?!)
