10 Most Underrated Parks And Recreation Characters

10. Mona-Lisa Saperstein

A late-term addition to the recurring cast of guest stars, Mona-Lisa (Jenny Slate) joined the show when Tom hired her to work for his clothes rental business Rent-A-Swag.

Twin sister to the equally infuriating Jean-Ralphio Saperstein (who himself describes her as a "total klepto, nympho and pyro"), Mona-Lisa is a spoiled daddy's girl whose father has sculpted her into a morally bankrupt dependant. So, yes, she's intolerable, she's annoying, she's the worst. But, like James Acaster says, the very fact of her being the worst is so impressive that she automatically becomes the best.

Fittingly, she makes her final appearance in the season seven closer "One Last Ride", but spends her screen time in the preceding seasons outdoing her brother in an all-out race to the bottom. Unafraid of saying and doing what she wants when she wants, Mona-Lisa takes over Tom's business and life, which thankfully helps him grow and gain some new perspective on where he wants to be, how he is going to get there, and who he definitely shouldn't be doing it with.

More than this, however, Mona-Lisa gives us some of the show's most straight-up shocking and laugh out loud moments, like inviting Tom and Ann to a threesome right after she has been dumped.
