We saw the grammar and civics ones when I was in school: never the math one, though.
I think the grammar one is the one most people remember/know best but "I'm Just a Bill" might be the most famous number of the whole series (and justly so -- I think it would be so even without parodies).
Kids at my school sang "constipation station, what's your location?" for "conjunction junction, what's your function?" Knowing how these things work I imagine it was widespread, stupid as it may have been.
