That's some strong wind. People have probably died in this wind and all Brutus cares about is his hat and coffee. People died, Brutus!
I'd take that as a compliment. The Batcave is awesome.
And I'd be totally fine making fun of Brutus' mancave because based on what we've seen, Brutus' mancave is basically just a TV and chair sitting in a lonely part of the house.
