I was recently taught a new card game called "52 card pick up". It's rather fun... for one person. Not so for the other. It consists of finding a victim and challenging them to a game. When they accept, you drop the cards on the floor and they have to pick them up again.
When this was done to me, I saw that all the cards landed face up in a relatively constrained pile. It could have been worse. I took a photo of it.
Anyway, the game isn't as good as geocaching, so stop thinking about playing cards and go find the cache.
