Hi, out there! Say, do you know what today is?

We'll give you a clue—actually, scratch that, you might be a little rusty after all these years, so we'll just tell you: It's the 20th anniversary of Blue's Clues!

Indeed, on this very day 20 years ago, a friendly cartoon dog named Blue and her affable human best friend Steve made their television debut of Nickelodeon. In no time at all, Steve (whose real name is Steve Burns) had kids playing Blue's Clues in living rooms across the country. Pre-schoolers were pumped to sing along and parents were thrilled to see their toddlers learning from the TV.
