T-I-O-N!!!

This is an Electric Company animated short about words that end in "tion," particularly the word "pollution."

When I was a little kid learning how to write I would run the "T-I-O-N!" refrain through my head to make sure I put the vowels in the right order and didn't spell "toin." I still play it in my head sometimes even though I haven't heard the song in more than thirty years. Until today, when of course I instantly found it on Youtube. Check it out.
