Today is National Grouch Day!
National Grouch Day was an invention of the now-defunct Sesame Street Magazine, a tribute to furry green Oscar of garbage can origins. Oscar the Grouch was noteworthy for his pessimism, the counterpart to the upbeat Big Bird.
"A Grouch's mission in life is to be as miserable and grouchy as possible, and pass that feeling on to everyone else. Only then will a Grouch feel in touch with his or her world and be happy."
