On Aug. 10, 1995 -- exactly 20 years ago today -- you could turn on your radio and, odds are, hear TLC's "Waterfalls" within a few minutes. It really was that immediate and it really was everywhere, but that's to be expected with the #1 song on the Billboard Hot 100 chart (where it reigned for seven weeks).
You couldn't escape the wonderfully aquamarine-tinged music video, either, and you didn't want to. No one wanted to. That was the point. That was also how "Waterfalls" won Video Of The Year at the '95 VMAs -- it was a perfect capturing of mid-1990s computer graphics blended with real, soulful, physical movement.
Sure, you could probably still sing along to the chorus. But how well do you know the entire song? Take our quiz below to find out -- and let us know how you do!
