Marlene

114里, Michael买了一大堆吃的去安慰被下属起诉性骚扰的Brian, 有下面一段对话:
B: Mmm, you know what I remember from high school?
M: The time in biology class when you beat off in a test tube for your science project?
B: No. Food. There was always lots of food at your house.
M: That's an Italian thing. And there was always plenty of booze at your house.
B: Yeah. Huh? That's an Irish thing.

An Irish thing是不是指Brian家是爱尔兰移民的后裔？他的母亲应该是天主教徒喽？
