My wife and I were in Las Vegas over the weekend watching a billiards tournament when she spotted a couple in the stands being very affectionate. 

The man was running his hands through her hair and passionately kissing the back of her neck.

My wife nudged me to look at the couple. After looking over at them, I said jokingly, “Now I don't know whether to watch them or the game.”

My wife replied, “You better watch them, you already know how to play pool.”
