Some of them were in series, and some weren’t. And you can find a bunch of them here. (I still have some of them memorized!)
My favorite Schoolhouse Rock picks are Interjections!, Rufus Xavier Sarsparilla and No More Kings.
Chopper (the Pushups in Peoria one)
Time for Timer! (You are what you eat, from your head down to your feet…)
A page about all of those PSAs. It’s amazing how completely I remember the lyrics once the songs start…it’s been at least 25 years!
Edited to add: Darn you, Kat! Darn you to heck!
Heh. That’s my favorite part, where it shows George III cackling like the maniacally evil monarch he really was! 
Poor George III, so maligned by Schoolhouse Rock. You could never get those made nowadays.
Does anyone remember the cartoon that sang about how great beans and rice were together, and how good for you they are?
Beans and rice, beans and rice…are nice
I guess it wasn’t a Schoolhouse Rock number, but something similar, and I remember it really well.
Aaaaand there it is, on the PSA list! Thanks! Don’t…drown your food! In mayo or ketchup or goo!
I’ve found myself humming the, “I’m just a bill” song for years. I never thought to youtube these. I just looked at the clock and lost an hour watching a bunch of them.
My favorites:
Victim of Gravity
Interplanet Janet
Electricity
I also quite like this video done in the style of Schoolhouse Rock:
The Schoolhouse Rock dvd collection is one of the few my kids have that I actually enjoy (that and all things Pixar). Hearing “3 is a magic number” again after 25 or 30 years made me tear up inexplicably.
Gotta go with “Conjunction Junction,” “I’m just a Bill” and “Interjection!” (I esp. love the nerdy guy in hornrimmed glasses cheering, “Hooray! I’m for the other team!” and everyone else in the stands menacingly turns towards him). Heh.
The best SR parody still belongs to this number, courtesy of The Simpsons.
See post #14.
Thank Goodness! I knew I couldn’t be the only one that on the ball. 
When I was a kid my absolute favs were Shot Heard Round the World, Figure 8 and My Hero Zero.
Something I just noticed after a ten billionth viewing is that the gnus coming off of Noah’s ark in “Elementary, My Dear” are holding a newspaper called the “Gnus.”
Strange, I’ve had this Complete Schoolhouse Collection for two years now and have never noticed the Money Rock section before. When did this stuff play? Watch for a cameo by Bill being menaced by a dinosaur that stands for the national debt in “Tyranosaurus Debt.”
Another interesting thing. I remember having to repeat the preamble as a test question in high school, and I could never have done it without the cartoon, which I had memorized, and I hadn’t heard for years.
But how the hell did I memorize it? Was I just impressionable? I can hear a current song 20 times these days and not know the lyrics.
This thing must only have been played once a week, at most. Did I just watch cartoons religiously enough that these brief educational segways would be repeated week after week?
Maybe it’s just that the Schoolhouse Rock tunes were incredibly, incredibly catchy.
The Money Rock shorts were done in the mid-90s. In my opinion, the music and animation for these is just as well-done as the originals from the ‘70s. (As for references to the classic shorts, note that one of the comics in the newspaper in "Walkin’ on Wall Street" is “Conjunction Junction.”)
Say, Anyone Remember NBCs try at this sort of thing? They used superheros to teach teh Metric system.
Now, they weren’t near the quality of SHR but as Metric is the system up here they were quite helpful.
Kids are generally much better at memorization than adults. Pokemon is a great example; it’s almost no effort for a kid to memorize 300 different characters and their attributes. And kids can often learn songs and poetry just by being exposed to something several times. Then it sticks. All that takes more effort in an adult, though of course you can still do it if you try. (Unless you’re my husband and just totally lack that skill.)
Well, to this day I will sing “I’m just a bill” or “Verb! That’s what happening!” for no apparent reason.
And when I need to remember the pre-amble to the Constitution, I hear the Schoolhouse Rock tune in my head.
I like them all, but my favorites are, Interjection and No More Kings.
A new favorite for me is Three is a Magic Number, but not the version from the cartoons. Two years ago, my daughter’s 2nd grade class did an extended rendition of it in a school musical, with all 100 or so kids doing synchronized body & hand motions. Normally, a 2nd grade musical looks just like a 2nd grade musical. But, during this performance–this song, the stars aligned in happenstance perfection. It was poignant. It was profound. And during the final repeat of the verse that starts, “A man and a woman had a little baby…”, I actually shed a tear.
Out of curiosity, when in your daily life do you need to remember the preamble to the Constitution?
So many favorites. The ones I remember best are the grammar ones (love “Adjectives,” love “Adverbs,” “Verb!” kinda scared me as a kid). Love “Figure 8” and really don’t have strong memories of the other math ones. I read a novel a while ago in which one of the characters has an obsession with all things Blossom Dearie. I thought that was a made up name, not realizing she’d performed “Figure 8” and “Adjectives.” Loved “Interplanet Janet” but it almost never seemed to air.
The creators put out an official guide to the series a few years back. It talks about each of the classic episodes (I think it includes the computer eps as well) except I think it leaves out the weather one that they got sued over. Very cool little book and worth picking up if you’re a fan.
It does. The weather song appears on the original VHS releases (which have bizarre little bumpers with Cloris Leachman), and finally reappeared on the DVD with the offending line removed. It’s actually quite catchy.
