I think Penn was going for the joke side of this to illustrate perception and irony. Both of these elements play huge roles in a comedian's life. People will always know the beatles, just because some 23 year old Montessori teacher from Texas had square parents doesn't mean huge elements within pockets of culture are meaningless. I'm going a little far here but you see what I'm saying, you need the people who don't know something so you can be one who does. Hell maybe she'll start listening to the beatles now and in a year know more than Penn?
