A unique phrase used twice becomes bland.

I once criticized Penny-Arcade for deviating from video game comics with "Cardboard Tube Samurai" installments, but now I realize as long as I'm not paying for it they can do whatever they want, especially when they look this gorgeous.

The latest PvP reminded me that I never understood what the phrase "Prisoners of your own butts" meant.

I am an idiot and I need someone to explain it to me.
