I don't get it.

The Far Side is easily my favourite comic strip ever, and makes me laugh-out-loud more frequently than any other comic, but I just don't get this one.  I've showed it to a bunch of people, and they don't get it either.  So what's the deal?  Clearly, it has something to do with the bowl of meat and the tattered state of the guy's house, but I just don't see the connection.  Someone needs to tell me what the joke is. 

And in case you're wondering -- no, there isn't supposed to be a caption.  I thought maybe it was some kind of misprint, but I checked another copy and there wasn't any caption there, either.
