Lyrics
Now let me tell you all a story of a truck-drivin' girl,

In a custom-made monster truck she took for a whirl!

That little speed demon gonna be a star,

With a learner's permit and an adult in the car!

She may be out for a lark, but she can't parallel park,

She's a truck-drivin' girl!

She's a truck-drivin' girl!

(Guitar solo)

Well someday she'll get her license and she'll have it all!

She can pick up her friends and take a drive at the mall

That little red-head gonna rock my world!

She's a truck-drivin' girl!

She's a truck-drivin' girl!

She's a tire-spinning, gear-grinding, clutch-burning', back-firing, paint-trading, red-lining, over-heating, throttle-stomping Truck-Drivin' Girl!

Background Information

 * This is one of the many times that Phineas and Ferb sing in a voice other then their own.
 * This song was nominated for the countdown but didn't get enough votes to be included. The lines which proceed it in its original episode ("That doesn't make any sense!"/"It doesn't have to! I've got a monster truck!") are present in the episode direcetly preceding song #7, (this time exchanged between Monogram and Doofenshmirtz) suggesting the creators originally thought it would make it.
 * In Disney's Phineas and Ferb: The Best LIVE Tour Ever!, this song is parodied as "Trick Drivin' Boy".
