I’ve had Sam and Max Hit the Road since probably around the time it came out, and I only discovered today that you can play it in black and white by pressing the ‘B’ key during play. Huh.

You can also turn on ‘dummy verb mode’ by pressing the ‘V’ key, which labels the actions in your inventory. If I recall the manual there’s also supposed to be built in screensavers, but I’ve yet to see them.
