I just had that same feeling the other day when I was listening to the song "Big Spender" as sung by Peggy Lee, and I heard:
The minute you walked in the joint
I could see you were a man of distinction.
A real big spender,
Good lookin', so refined.
Say, wouldn't you like to know
What's goin on in my mind?
So let me get to the point.
I don't pop my cork for every guy I see.
Hey big spender,
Spend a little time with me.
Pop my cork? For some reason the phrase "spread my legs" just fell right into my mind as I listened to it. It made me laugh, though at the same time also made me think "Either I have a dirty mind, or I am slow...or both..."
ZZ Top: Pearl Necklace and Sharp-dressed Man also come to mind.
