Like most things, the show tarnished a bit with age, but what I remember most was that this show could be watched by people who only spoke one or the other of English and Spanish, and still be enjoyed and understood.
I was in high school when this show was on PBS in the NYC area, and my father's mother was living with us. My grandmother and I were watching the show and laughing till we choked, some slapstick scene with the grandmother and the dishwasher is all I remember now, 30 yrs later. What I remember most vividly is my father walking into the TV room to find his youngest kid and his mother laughing themselves sick, over a Spanish language TV show when neither of us spoke or understood Spanish. He talked about it for days, told everyone he knew at work about it. All we could tell him was, "it was FUNNY!"
