Sorry. I Mistake You for Someone With a Brain

I don't think Brutus is making these mistakes on accident or even on purpose. I think Brutus is suffering from a series of mild strokes that will soon render him as useless as Stephen Hawking except Hawking at least still has his amazing brain while Brutus, let's be honest, does not.

Also it looks like Veeblefester is also having a mild stroke in the last panel. Heh. Thornapple will do that to you.
