what's a commercial from your childhood you just can't forget?

An Anacin (headache medicine with aspirin in it) commercial with a young woman and her mother. Her mother was trying to help her do something and she snapped at her mother and yelled “Mother, I can do it myself!” She had a headache and took Anacin and it went away and she became civil to her mother again. This commercial was mocked on talk shows.

The other one was the Rice-A-Roni commercials showing streetcars with the jingle “Rice-A-Roni, the San Francisco treat”
