Guests learn pretty quickly on the set that they do not get to speak to the host unless he wants to engage with them. Ex-contestants have revealed that Trebek only speaks to them whenever the lights are on, cameras are ready, and someone yells action. When Trebek is on his own time, you better leave him alone!

Knowledge is important for the show, obviously, but so too is timing.
