Phineas & Ferb Cast - A Better Best Friend Lyrics

Today I've learned a lesson,
What a best friend should do.
I put busting my brothers
Ahead of you.
You were always there for me,
On you I could depend.
And now, too late, I realize
I should've been a better best friend!
(Ooh-wow-wow-wow-wow)

I said things I shouldn't have,
Did things I shouldn't do.
Guess I forgot that you cannot
Spell Us without "U."
(Oooh-wow-wow-wow-wow)
