Brain Game: A Blank Look

There are many words that you could place in each blank to make different terms. If you choose the correct ones, however, you'll notice that the four words you use to fill in the blanks have something rather obvious in common. Can you name them (and identify what they have in common)? Good luck:

COUNTRY _________ BASEBALL __________ PURPLE __________ DAVID __________

Here is our SOLUTION.

THE SOLUTION:

COUNTRY CLUB, BASEBALL DIAMOND, PURPLE HEART, DAVID SPADE.

The four words used to fill in the blanks are the four suits in a deck of standard playing cards.

Did you come up with a different solution? Please post it in the comments. Thanks!
