Corn hole. You've probably played it.

I recently enjoyed helping a client - who has a cool and distinct, minimalist approach to design - create a birthday invitation for her father's surprise birthday party along with a dozen cupcake toppers. 

Part of the invitation invites guests to enjoy the cookout with "corn hole."  Until this project, I had no idea what corn hole was, but later found out it's essentially an organized bean-bag toss game.  And now you know, too.
