Mutts' excessive white space.
Per the usual, Sunday is a big day for silent penultimate panels.

So what about today's Mutts?
Patrick McDonnell, more than anyone else working in comics today, is a master of comics grammar. If he does something unusual with his layout, it is for a good reason. But as far as what purpose this sea of white space serves, I have no idea. It does indicate a major passage of time, but I don't see how it serves the joke better than a standard series of time-passing panels would have. I will just assume that I'm missing something here.
