October 15 is National Grouch Day in the world of Muppets and a day for grouches to celebrate their grumpy way of life, according to Sesame Street Magazine.
What exactly makes a person a grouch? “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. Yet, even though a Grouch may show happiness at anyone’s misfortune (including his or her own), a Grouch would never admit to being happy. Such is the stability of a Grouch’s life: so balanced, and yet so unbalanced,” states Muppet Wiki.
Some scientists say being grumpy can actually be a good thing, as research shows grouches are usually better at decision making and are less gullible. Researches also say sourpusses seem to cope with tough situations better and are more attentive.
