I was out christmas shopping in John Lewis last week (read: looking at the pretty expensive things) with a friend who's completely loaded, and he was going on about which of the pens he wanted. Of course, it was the most expensive one, so I came out with, "Yeah, it's not cause it's the most expensive, is it - it's cause it costs more!"
He didn't even think it weird. I don't know if that says more about his pop culture knowledge, or his wallet!
