Nate and Marni are at a dinner party with Bowie's parents when Marni realizes that she has never met Nate's mom. Nate eventually agrees to let Marni see her.
They visit her home and Marni eventually realizes that they aren't in a house but in fact an asylum. Nate leaves and Marni tells his mom, Lily, that she really loves her son. Lily then tells Marni that she doesn't like her.
Marni is upset, as normally everybody likes her. She goes back to see Lily, who tells her that she'll like her if Marni breaks her out of the asylum. Marni does so.
Later, Marni tells Nate that she broke his mom out of the asylum and then lost her at the Guggenheim museum. Nate is annoyed at what Marni has done. Nate and Bowie search the Guggenheim for Lily and eventually find her pinned to a coat-hanger. They get her down and return her to the asylum. Nate and Marni reconcile.
Meanwhile, Tess meets a cute guy in the elevator and asks Clown to help her get a date with him. In exchange for some tomato juice, Clown tells the cute guy that Tess is "easy" and she gets a date with him.
