Not necessarily un-pc, but not many teachers would appreciate the song I sang at our pre-school graduation.
"Show me the way to go home
I'm tired and I want to go to bed
I had a little drink about an hour ago
And it’s gone right to my head
Everywhere I roam
Over land or sea or foam
You can always hear me singing this song
Said show me the way to go home."
My grandmother always sang it to us with hand motions for "knocking one back" and how it had "gone to our heads" parts.

She about died when I jumped up and said I had a song I wanted to sing for everyone! Perfect song for a four year old girl to sing!
