Lyrics
Hamilton Hocks: I see a square up in the air four equal sides and corners fair. I wonder why a square is there. But still, it is okay.

Pip and Pop : Okay.

Hamilton Hocks: This rectangle I've seen before Unequal sides and corners four Its shape reminds me of a door I've looked at shapes that way.

Pip and Pop : That way.

Hamilton Hocks: But a triangle is a thrill to see Three lovely sides and corners three It look like poetry to me I looked at three sides now They made me say "Oh, wow!"

Pip: A triangle.

Pop: Far out!

Hamilton Hocks: A circle is one side that bends around and around that never ends. With circles, I'm the best of friends They're useful as can be.

Pip and Pop : Can be.

Hamilton Hocks: A circle can be many a thing A hoop, a tire, an onion ring, but circles don't make my heart sing to triangles I bow. A triangle is a thrill to see Three lovely sides and corners three It look like poetry to me I looked at three sides now They made me say "Oh, wow!"

Pip: A triangle.

Pop: Oh, wow!

Hamilton Hocks: Oh, wow!
