Alabama Sandwich Preference

Alright, listen up, you're not the sharpest tool in the shed, are you? You posted this little gem, and it's a play on words. It uses the phrase "in bread" as "inbred". Alabama has a stereotype that people from there are inbred. The humor is that the joke is using a different meaning of the phrase. It's a common trick. Pretty straightforward even for a blockhead like you.
