digging through the archives I found this great late 80s sitcom

over twenty epsidoes available..including the complete Brady bunch paraody...

It ran from  2/88 to 6/89, on nbc. Day by Day was a  SPINOFF of sorts to FAMILY TIES as it was revealed that the family patriarch, Brian Harper (played by Sheehan) was a college roommate of Steven Keaton A total of 33 episodes were produced.

The show centered around a married couple with successful careers (he as a stockbroker, she as a lawyer) and a teenage son. After the couple had a second child, they decided to quit their jobs and open a day care center in their home. The episodes mixed stories about the day care center with those about the teenager and his friends. Louis-Dreyfus played a materialistic neighbor, while Thorne-Smith played the baby's nanny.

THE FAMOUS BRADY EPISODE

Ross falls asleep, and finds himself in the opening credits of The Brady Bunch. Ross learns that he is the Bradys' long-lost son, Chuck. After he gets his hair permed at Mike's suggestion, he visits with the various family members, who reprise some of the scenes in the Bradys' most famous episodes ("Oooh, my nose!", the Buddy Hinton episode, etc.)

After "Chuck" gets some advice about his poor grades from Mike, the family begins to repeat their dialogue. "Chuck" wonders what's amiss, and Mike explains what he's seeing is a rerun. Everything becomes chaotic, and Ross wakes up, vowing to improve his study habits.

Barnes would later portray Greg Brady in the brady bunch movie

 Day by Day centered around the Harper family. Brian Harper, a stockbroker and Kate Harper, a lawyer, decided they wanted to spend time with their children so they decided to end their careers and open a day care center in their home. Ross Harper was their son, who was into girl chasing and being independant and wasn't happy about his father wanting to spend time with him.
