Here we find Treat Yo Self Day, as invented by Parks and Recreation‘s Tom Haverford and Donna Meagle. Your own annual Treat Yo Self Day can fall on any day that you so desire. That’s the glory of Treat Yo Self Day — it’s a day to treat yourself to exactly what you need. Clothes? Fragrances? Massages? Mimosas? Fine leather goods? Treat yo self. It’s the best day of the year! That is, unless you find yourself stuck with a depressed Adam Scott in a Batman costume.
