Passage: Pete is a former advertising executive living a Beatnik–Bohemian life in a loft in New York City. Since living in the commune, Pete has turned into a cynical, misanthropic artist. The members of the commune are seemingly aimless, indolent or melancholy while waiting for the world to end; one member lives her life in a burlap sack, with only her bare feet protruding.
One day, a wayward toucan arrives at the loft. The toucan, which stowed away on a Greek banana boat from South America, carries a unique and highly contagious virus. The virus causes intense feelings of giddiness, happiness, and kindness in anyone affected by it.
Pete initially catches the virus and in an outbreak of euphoria, suddenly senses a purpose in his life. Pete's girlfriend Liz is initially horrified at his behavior change, and when she learns from nearby police about the bird's virus, tries to warn him, but he has already shaved his beard off and proposes marriage and conventional living. Pete plans to trick her and the members of his loft into getting infected, by pretending to be the nihilist German philosopher leader of a doomsday cult popular in the commune, and spreading it through close facial contact with them. In his disguise, he convinces Liz to let him kiss her, but he is soon revealed as himself. 
The now upbeat collective keep the toucan, nicknaming it "Amigo". They then decide to spread the virus to as many people as they can in New York City, disguising themselves in conventional dress. Liz remains physically immune, but the positivity she encounters from her friends leads her to respond in kind. When authorities show up to catch the bird, Pete and Liz spirit him away by Liz hiding him in her dress and pretending to be pregnant, though the ruse is complicated when "nice" police take the couple to a hospital to give birth. 
Question: What are the first names of the couple who go to the hospital to give birth?

Liz.
