[The stage is set with a vibrant backdrop featuring question marks in various sizes and shades. The host, smiling, walks onto the stage, waving to the cheering audience.]

Host: Ladies and gentlemen, welcome to "The Riddler Unraveled!" Tonight, we have a special guest who needs no introduction. He's the mastermind behind some of Gotham's most perplexing puzzles. Please give a warm welcome to the enigmatic and elusive, The Riddler!

[Applause erupts as The Riddler confidently strides onto the stage. Dressed in his signature green suit adorned with question marks, he flashes a mischievous grin.]

Riddler: Ah, it's a pleasure to be here, but do you mind if I start with a riddle for our esteemed audience?

Host: Of course, Riddler! We wouldn't expect anything less.

Riddler: Alright, here it goes. What has keys but can't open locks? You may find it attached to a clock.

[The audience murmurs, pondering the riddle.]

Host: Hmm... A piano?

Riddler: Correct! Bravo! You see, life is full of little mysteries waiting to be unraveled.

Host: Speaking of mysteries, you've been quite the puzzle for Gotham's finest for years. What motivates you to concoct your intricate schemes?

Riddler: Ah, the pursuit of knowledge, dear host. Every puzzle I create is a testament to the human intellect. Besides, what's life without a little challenge?

Host: Fascinating! But tell me, do you ever feel remorse for the chaos you cause?

Riddler: Remorse? Ha! My dear host, I'm merely providing a service. I challenge the minds of Gotham's citizens, pushing them to think beyond the ordinary. Besides, where's the fun in being predictable?

Host: I suppose unpredictability is your forte, Riddler. Now, let's talk about your latest caper. Rumor has it you've devised your most elaborate puzzle yet. Care to shed some light?

Riddler: Ah, but where's the mystery in that, my dear host? Let's just say Gotham is in for a mind-bending experience unlike any other. But fear not, for every riddle has a solution... for those clever enough to find it.

Host: Intriguing! Well, we're certainly on the edge of our seats waiting to see how it unfolds. Unfortunately, that's all the time we have for tonight. But before we go, any final riddles for our audience?

Riddler: Of course! Here's one to ponder: What comes once in a minute, twice in a moment, but never in a thousand years?

[The audience murmurs, trying to solve the riddle as the camera fades out, leaving them with The Riddler's challenge echoing in their minds.]

[End scene.]
