Can you keep a secret? Though this looks like only one puzzle, it's actually two.

Granted that wasn't exactly the secret of a lifetime, but we can't imagine you're here seeking the answers to all of life's questions. (And if you are, they were already here and you just missed them!)

The grid below has 20 mystery squares. Click on any pair of squares to reveal two coins. Match the coins and we'll reveal part of the picture underneath the grid. If the coins don't match, we're going to cover them back up. Keep going until you've uncovered 10 coin pairs.

And by the way, a nickel isn't always a nickel, nor is a dime always a dime. For all coins below, the sides have to match as well as the denomination. Heads and tails do not a match make.

Once you've matched all of the coin pairs, a rebus will completely reveal itself. Your job is to decipher this somewhat famous yet anonymous saying.
