I do sum, I do sum
I do sum times you don't
My heart goes pump, pump, pump
So I can run and jump
(Chorus)
I do sum, I do sum
I do sum what you don't
I run and jump and play all day
That's what I do today
(Verse 2)
I like to sing, I like to dance
I like to laugh and prance
I like to play with all my toys
And make a lot of noise
(Chorus)
I do sum, I do sum
I do sum what you don't
I run and jump and play all day
That's what I do today
(Bridge)
I do sum that you don't do
I'm a kid, and that's what I do
I have fun and enjoy my life
And I'll never stop
(Chorus)
I do sum, I do sum
I do sum what you don't
I run and jump and play all day
That's what I do today
(Outro)
I do sum, I do sum
I do sum, so don't be mad
I'll keep on doing it
Until I'm big and old
