Phineas: And a true testimate to how a great mom you are, we like to present, this song.
Candace: Mom it's your birthday. Thanks for all the care and love you give. Not to mention the meals, but times I get kinda nervous. And forget to tell ya how I feel. (Phineas & Ferb: Shoo-be-do-shoo-be-do)
I'm a little high strung, it's just because I'm young, mom I adore ya. And I'll do anything for ya.
Although my brothers make me frantic. With every single crazy antic. And when I'm bouncin' off the walls, you're the one who stays calm! (You're the one who stays calm)
Because you love me, for who I am, I'll always love you mom.
