What the Hell, Beatles?

Intro
I still wonder what the hell this song was about--it always seems to me those guys were too young for these lyrics, unless they were channelling from their ancestors.

Girl

Is there anybody going to listen to my story All about the girl who came to stay? She's the kind of girl you want so much it make you sorry Still you don't regret a single day Ah, girl, Girl, Girl When I think of all the times I tried to hard to leave her She will turn to me and start to cry And she promises the earth to me and I believe her After all this time I don't know why Ah, girl, girl, girl She's the kind of girl who puts you down When friends are there You feel a fool When you say she's looking good She acts as if it's understood she's cool, ooh, oo, oo, oo Girl, girl, girl Was she told when she was young that pain would lead to pleasure Did she understand it when they said That a man must break his back to earn his day of leisure? Will she still believe it when he's dead Ah, girl, girl, girl Girl
