Getting Acculturated

My Culture, Literature, and Language of Ireland professor (actually called a lecturer here, a professor is the head of a specific department) is exactly what you expect an old Irishman to look like. Short, pale with reddened cheeks and frazzled, thinning red hair. He's also hilarious, and spends half the class making jokes. The following is a gem of a conversation. First, a little background. Irish classes are scheduled from the beginning of an hour to the end of an hour, with no passing period. Since it would be unreasonable to expect people to be there at the exact times, most classes start 5-10 minutes into the hour. The lecturer walked into class yesterday at 6 PM, looked at the full room, and said: "Wow, everyone's on time. That's so un-Irish of you."
Me: "Give us a few weeks, we're not adjusted yet."
Lecturer: "Ah, yes, in a few weeks you'll all be acculturated and come late. Then you'll be drunk, too. But that's not a problem, it will make the lecture better."
