They "GET" Neither The Beatles Nor Sarcasm in Dixie

Actual conversation that took place today.

I send a daily stats email to employees daily. I always include trivia or a name that tune sort of thing, for fun - to break up the drudgery etc. Today's email was including a line from PENNY LANE.

One of the girls came of and said she didn't know the song - what was it?

The exchange went like this:
Me: Penny Lane, by the Beatles.
Her: OH....I don't really like the Beatles, I only like classic old stuff like Zeppelin. Not new stuff.
Me: Ummmmm, the Beatles? John Paul George Ringo?
Her: Right. I don't really like new music.
Me: You know the Beatles came out like 40+ years ago right?
Her: Oh is that when they started?
Me: Yeah they broke up like 71 or 72.....John Lennon was murdered in 80 so I don't think I'd really call them NEW.....
Her: Oh he got murdered? Which one was he?
Me: The English one. (the sarcasm begins HERE for you southerners)
Her: Wow what happened was it random?
Me: No he was murdered on purpose by a psychopath named Mark David Chapman who did it to be cool or some bullshit.
Her: WOW how do you know all this did you know him?
Me: Yeah.....we had the same birthday. (true, we do/did).
Her: Were your mom's in the hospital at the same time?
Me: Ummm. No.

At this point I exit to the stage left so I don't pee my pants laughing as my stone face was cracking.
