Daniel Tiger: When something strange happens, and no one knows why, you need a great detective, and I'm that guy. When someone did a crime, but you don't know who, you call a great detective to find out who for you. Who solves the mystery? Who finds out? Me, the great detective! And when I do I shout...Aha! When I find a clue. Aha! That's just what I do. Aha! That's the word I yell. Yes, I'm the great detective,and here's how you can tell, aha! Got a mystery on hand, on your feet, or on your head? Well, don't just stand there. Call me instead! With my great detective hat, and my great detective mind, and my magnifying glass, there's no answer I can't find. The who, what, when, where, why, and how! I'll answer every riddle, I'll follow every clue! Aha! That's just what I say. Aha! When I've saved the day. Aha! In a British voice. You need a great detective, I'm your number one choice! Aha! Aha! Aha! Aha!
