We laugh a lot in our house. If you told me there was a study that proved that laughing makes people 100% happier I would believe you. It is hard to be sad or upset when you are laughing. Anthony Robbins talks about how psychology follows physiology. If you act happy your mind has no choice but to assume you are happy. I live by this rule because it works, even in the worst times.
PS- the title references a classic nonsensical line in the movie Anchorman.
