Rocky Raccoon is pretty ridiculous, as a character, and I randomly got really. really. angry with him yesterday while we were traveling from Mexico* to Maryland. The song got stuck in my head, and the more I thought about the lyrics, the more annoyed I became.
The guy really needs therapy.
First, he's in love with a woman who has a multitude of names, which seems pretty shady to me. Why can't you love someone who's honest, Rocky? Why? Second, she left you for another guy. A relationship can't work if only 50% of the people want to be in it, man. Third, if she's the kind of girl who WOULD fall in love with you because you murdered her boyfriend? Well...kind of a red flag, I should think. You can't blame the other guy for Magill (or Lil or Nancy or some other alias) falling for him. Maybe you should've been a better partner, and focused on her needs, rather than violent vengeance.
Just try to like you for you. I'm sure you'll find a nice, succinctly-named girl in no time.
