**unsure** ............. and i'm on my last rag

The story:

This was a friend's intelligent deduction, actually,
and the conversation went something like this:

Me: Why do Trace Adkins and Jule Roberts have the
same song on their new albums? "I'd Sure Hate to
Break Down Here?"
Keith: Oooh yeah... like it but I don't ilke when she
mentions the rag
Me: Uhh, I don't recall that part
Keith: She said "blah blah and I'm on my last rag" or
somethin' in the first verse
Me: NOOOOO! You idiot!! It's "I'm out of
cigarettes... and I'm down to my last drag!"
Keith: Ooooooh okay, cool, I can like that song
now.
