Interestingly enough, “Three’s Company” was actually based off of a British show from the 70s called “Man About the House.” “Man About the House” centered on two female roommates who (after a night of partying) wake up to find a man asleep in their apartment.
The three later become roommates, exactly like “Three’s Company!”
