I dunno if they do it anymore, but when the second player comes out for Fast Money, Steve will say "Your partner did pretty well...(s)he got you 142 points...", and the audience will cheer................like they didn't just see the partner score 142 points two minutes ago! I'm beginning to think the audience coordinators think silence would make the show seem boring.
I think somebody around here timed it out once that the Family Feud audience responds with cheers, applause or both about every fifteen seconds, or some small amount of time like that.
It's been symptomatic in the industry for quite some time now if your game is not "serious business." At the Wheel tapings I attended a few years ago, I tried to keep up with all the points where you'd hear the audience applause. Before the end of six shows, my wrists hurt.
/Strangely enough, one place where they don't want you to applaud is when the bonus wheel is spinning. The applause you hear then watching the show is a hundred-percent canned.
