"What a Big Mistake" is an original Barney song that first appeared in "Making Mistakes".
Lyrics[]
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/Can’t Learn!)
Yes, you can learn from your mistakes.
Triva[]
All of the dinosaurs (Barney, Baby Bop, BJ, and Riff) have made mistakes and sang this song.
In "Making Mistakes", BJ gave the caboose a fresh coat of paint using a variety of colors for "Make the Park Pretty Day", even though it is supposed to remain red. In "Sharing", Riff accidentally wrecked BJ's scooter. In "Fairy Tales", Baby Bop (as Pandora from "Pandora's Box") opened a box that wasn't supposed to be opened and caused her and her friends to be covered in blue, itchy spots. In "Pistachio", Barney had a pistachio addiction. In "To Catch a Thief: A Mystery Adventure", BJ falsely accused Riff of taking all the park's balls.
Excluding archival footage, BJ sang this song twice.
