Which makes one wonder why the penny-pinching producer paid for the rights to a format that he really isn't using (assuming he did; maybe the whole thing is in the public domain by now). He could just as easily have done the same show with a different title. It's not as if the original show had a legion of fans just begging for a revival.
I don't think Byron paid anybody for the rights to anything. As far as he's concerned, this is his own original show.
Also, I can't tell specifically if you're referring to the obscure 60s game
Funny You Should Ask or not, but I've seen several people on Facebook claim that this is a remake of that (including an overeager Wikipedia editor), and that's just not the case. Aside from the title, and the fact that the celebrities seem randomly strewn around the set, the two shows are not the same game. Just as there are several completely different shows that are called
Break The Bank, and a 50s game called
Wheel of Fortune that has nothing to do with Hangman, this is just a different show that happens to use a common phrase as its title. It wouldn't surprise me at all of Byron was completely unaware the earlier show with that title even existed.
