Jean-Ralphio is undoubtedly one of the best parts of Parks and Recreation, and it looks like now we're about to meet his sister. According to EW, the series has tapped former Saturday Night Live star Jenny Slate to appear in an upcoming episode as Mona Lisa, the same-age sibling to the character, who is portrayed by House of Lies star Ben Schwartz

Even better, the circumstances of her appearance already sound more awesome than her name legitimately being Mona Lisa: Tom (Aziz Ansari) will hire her to work at his new business Rent-a-Swag, and it won't end well because she, like her brother, sucks at holding down any job whatsoever.

Slate's episode will air sometime later this season.
