When you're 4 or 5 years old 
It's really hard to make up your mind 
What you want to be when you grow up 
After all you do have a lot of choices 

I might drive a truck, I might drive a train 
I might sail a boat or fly an airplane 
Might take a rocket ship to the moon 
I'm growin' pretty fast so it might be soon 

When I get big, when I get big 
That's what I'm gonna do when I get big 

Someday I'll leave mom and dad all alone 
Make a lot of money then come back home 
I'll buy everybody everything they like 
I'll even buy myself a brand new bike 

When I get big, when I get big 
That's what I'm gonna do when I get big 

I might be president and stop all the wars 
And make people happy wherever they are 
Protect all the animals, the dolphins and the whales 
If people try to hurt 'em, I'll put 'em in jail 

When I get big, when I get big 
That's what I'm gonna do when I get big 

When I get big, when I get big 
That's what I'm gonna do when I get big 
When I get big, when I get big 
That's what I'm gonna do when I get big
