5. Treat Yo Self! ('Parks and Recreation')
This strong choice for the greatest Tom Haverford line ever has become something fun to bark at office mates, as well as an ongoing, self-pleasuring [ahem] movement among Parks and Recreation fans. An exhortation between Ansari's would-be ladies man-slash-hapless entrepreneur and his partner-in-crime Donna Meagle (played by Retta), this phrase marked a day of shopping and other activities designed with personal indulgence and maximum pampering in mind. While it may not have contained one of Haverford's signature, half-baked business ideas or highlighted his knack for ad-libbing, the cartoonish swagger of the "treat yo self" moment reinforced the comic's ability to propagate a catchphrase.
