What sit-coms employed the ol' smart sibling - dumb sibling chestnut?

I think Family Ties was the first here's others I can think of:

Growing Pains

The Simpsons

Married with Children

Step by Step

The Married with Children rip off with the talking stuffed bunny

Family Guy

Malcom in the Middle



Only one of the above had a dumb sister and smart brother: married w/ children. The rest were dumb brother.



Am I missing any?
