Task: Question Answering
Input (English): Passage: Wealthy Yemeni-American brothers Steve and Doug Butabi enjoy frequenting nightclubs, where they bob their heads in unison to Eurodance, a subgenre of dance music, and fail miserably at picking up women. Their goal is to party at the Roxbury, a fabled Los Angeles nightclub where they are continually denied entry by a hulking bouncer.
By day, the brothers work at an artificial plant store owned by their wealthy father, Kamehl. They spend most of their time goofing off, daydreaming about opening a club as cool as the Roxbury together, and Doug using credit card transactions as an excuse to flirt with a card approval associate via telephone that he calls "Credit Vixen." The store shares a wall with a lighting emporium owned by Fred Sanderson. Mr. Butabi and Mr. Sanderson hope that Steve and Emily, Sanderson's daughter, will marry, uniting the families and the businesses to form the first plant-lamp emporium.
After a day at the beach the brothers decide that night was to be the night they would finally get into the Roxbury. Returning home, Doug gets into a heated argument with their father about going out clubbing instead of staying home. Their father has planned a dinner party with Emily and her parents. The angered Mr. Butabi then refuses them access to their BMW car and their cell phones. They are given enormous cell phones by their mother, Barbara, and allowed use of the fake-plant store's delivery van, but they are immediately rejected once again by the doorman. 
Question: What are the first names of the people who spend most of their time goofing off?
Output (English): Doug.
