DO NOT DISTURB

I know better – from bitter and hard-won experience – than to disturb Wilson when he's behind a door displaying a sign like this!
His brother Byron (pictured here) knows better than to risk the wrath of the inventor at work, and I think even Wilson's constant companion Antony would think twice before knocking…
I dread to think about what Wilson might be 'inventing' – but I can safely predict that:
(1) he thinks it will make him very rich, and
(2): I'm not going to approve.
Beyond that, I can only wait in trepidation and fear the worst…
