What a Big Mistake is an original Barney song that first appeared in Making Mistakes.


Oh! Oh! Oh! What a big mistake!

No! No! No! Look my knees have started to shake.

Whoa! Whoa! Whoa! This is more than I can take.

Oh! Oh! Oh! What a big mistake!

I thought things were going ok, but they turned out wrong!

And I hope everything works out before too long.

But, until they do, I'm gonna sing this song.

Oh! Oh! Oh! What a big mistake!

So. So. So. You made a big mistake.

No. No. No. You don't need to shiver and shake.

All you need to know, for goodness sake.

Is that you can learn. (I Can Learn!)

Yes, you can learn from your mistakes.
