how does firoozehs use of humor to describe her experiences as an iranian immigrant in america enable you to apreciate the more confusing or mystifying aspects of american culture

The humor is gentle, dry, and full of irony. Consider Nematollah's space suit. Nematollah was trying to lose weight in order to attract women. He purchased a "space suit" from NASA which was designed to make him sweat out weight for a couple hours a day, but to speed up the process he didn't take it off. This resulted in him smelling particularly sweaty and awful which ironically repelled everyone rather than attracting a pretty girl.
