Busted down on Bourbon Street.
Set up like a falling hen.

The story:

I was doing singing valentines with my school choir and my best friend and I were singing. Being a choir member, and all confident with my singing skills, I was belting it out as we walked back to the bus with my best friend and the minute I sang it, I realized what the real lyrics were. My best friend couldn't stop laughing and I felt really stupid.
