Have you ever seen or heard of the old sitcom, One Day at a Time?

It apparently ran from 1975-1984. It's funny, I love really old sitcoms and have seen lots of them since I was a kid like Family Ties, The Facts of Life, The Brady Bunch, The Jeffersons, All In The Family...but I didn't even know that [i]One Day at a Time[/i] even existed. Kind of surprising, considering how long it ran.
