Things like this in China make me laugh.  "Happiness" toilet paper.  I never really thought about toilet paper making me happy, but when I saw these rolls of "Happiness" I realized that I'm less happy without toilet paper or when toilet paper is in short supply (thinking back on my trip to Tibet).  So I suppose you could conclude that toilet paper indirectly makes you happy since a lack of it makes you less happy.  And Chinese bathrooms which inevitably are without toilet paper are definitely less happy to use than bathrooms in America.  "Happiness" toilet paper is actually a good brand, in case you're wondering.  So, happy everyday and every trip to the bathroom.

Double Happiness
