A friend and I recently had the memory of this scene happening on Diff'rent Strokes because it's the way we both remember the periodic table symbol for gold! Now... There is a scene from the facts of Life which has this exact situation happen and Tootie says this line. The clip is on YouTube and such. But my friend and I both swear it was Diff'rent Strokes as he never even watched The Facts of Life. This is killing us and we need help finding out if we are making up some memory that doesn't exist or we actually saw this on Diff'rent Strokes. Any help would be appreciated!
