When you're five years old   And you walk downstairs   And catch your parents on the couch   Playin' some game   That looks like half-dressed mouth-to-mouth   Well it's a shock to your system   And your brain starts spinnin'    And you make yourself a pact   When I grow up   I ain't ever gonna do that      Chorus   Yes, you will   If your lucky you will know just how that feels   You step into a pair of shoes   That you swore you'd never fill   You say you won't   But Yes, you will      'Fore long you got    Your drivers liscence   And the world seems like it's yours   Except for the fact   That you've got to be home by ten of course   And that makes you mad so you throw a fit   And slam the door as you leave the house   You yell "when I have kids   I'm not gonna care    How late their out"      Repeat Chorus      Well you know how your grandma and grandpa   Are happy just sittin' 'round the house   Wearin' clothes that are out of date   Talkin' 'bout the old days   And draggin' photo albums out   And you sure do love them    But I mean come on now   You won't ever be that way      Repeat Chorus      Oh you can say you won't   But yes, you will
