When I was a kid, I watched Sesame Street all the time. My favorite character from the show is still the grumpy green monster that lives in a trash can- Oscar the Grouch.
On this isn't happiness, I saw these funny instructions from Oscar on learning to be miserable. It's like a Grouch version of a Zen koan, a paradox or unsolvable riddle.
They are from a kid's book & record set called "How to be a Grouch". It's an entertaining look into the life of a Grouch, like Oscar.
