A girl told me "then you can send me cracker jacks!"

what does it mean? She told me "it has been in some pretty old song lyrics... you have to figure it out"

Any ideas? that is all i know...

Thanks a lot

and if it helps at all...

she listens to john mayer, celine dion, and sugarland... among others...

Try Tin Pin Alley - Take Me Out to the Ball Game
If Wikipedia is to be believed this song has its origin in 1908/1927

Take me out to the ball game,
Take me out with the crowd;
Buy me some peanuts and Cracker Jack,
I don't care if I never get back
