P-File: "I Wonder What's Under a Scotsman's Kilt" p. 48
Tune: Typical Scotish brogue

I wonder what's under a Scotsman's kilt
A-wang, a-wang, a-wang, a-wang
Tickle me, tickle me, you know where
Under my kilt and in my hair
But if you tickle me in the wrong place
I'll lift up my kilt and I'll piss in your face.
