Phineas i Ferb - Your my better best friend

Female Singer: Today I've learned a lesson, what a best friend shouldn't 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.

I said things I shouldn't have, did things I shouldn't do.
Guess I forgot that you cannot spell "us" without "you"

Buford: So you lost your best friend, huh? Yeah, I know how you feel. I lost my best friend once. Little guy, all yellow-y and scaly. His name was Biff, turned into a whole brouhaha. I had to fight a squid.

Female Singer: Today I've learned a lesson, what a best friend shouldn't 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!

I said things I shouldn't have, did things I shouldn't do,
Guess I forgot that you cannot spell "us" without "you"

Buford: So, you lost your best friend, huh? Yeah, I know how you feel. I lost my best friend once. Little guy, all yellowy and scaly. Turned into this whole bruhaha. Had to fight a squid. Heh, guess I'm not makin' much sense. Kinda lost my train of thought. Anyway, the verse is comin' back around. Enjoy!

Female Singer: You scratched my back
You blessed my sneeze
Now I know that best friends
Do not grow on trees

You're always there for me, on you I could depend
Now too late I realize, I should've been a better best friend
I'll never have a better best friend
I'll never have a better best friend
I'll never have a better best friend
