(verso 1)
They say I need some Rogaine to put in my hair
Work it out at the gym to fit my underwear
Oakley makes the shades that transform a tool
You'd hate for the kids to think that you lost your cool

 F#5                   C#5
I'ma do the things that I wanna do
 D#5                   B5
I ain't got a thing to prove to you
F#5                       C#5
I'll eat my candy with the pork and beans
D#5                    B5
Excuse my manners if I make a scene

I ain't gonna wear the clothes that you like
D#5                  B5
I'm fine and dandy with the me inside
 F#5                       C#5
I look in the mirror and I'll take a peak
 D#5                      B5
I don't give a hoot about what you think

(verso 2)
Everyone likes to dance to a happy song (Hey, hey)
With a catchy chorus and beat so they can sing along (Hey, hey)
Timbaland knows the way to reach the top of the charts
Maybe if I work with him I can perfect the art

 F#5                    C#5
I'ma do the things that I wanna do
 D#5                   B5
I ain't got a thing to prove to you
F#5                       C#5
