Porky Pig
While Daffy is prepping up another scheme to prove his identity as Robin Hood, there's a brief moment where Porky sings this song that doesn't register in my head. It sounds like a gag, but i never got it.
"There was a time, when I was young, there was a fair maid dwellin'. <something something something>, oh what a day, her name was barbara allen."
Can anyone explain who Barbara Allen was, and how this joke makes sense?
