[Back to the Future] So, my friend from high school, Lorraine, had this short fling with this guy, Calvin, before she ended up with her eventual husband, George. But their son, Marty, looks a lot like Calvin. Did Lorraine cheat on George? Should I say anything?

No, you should not say anything. 

It's been thirty goddamned years, Karen. You've been nursing this sick little theory for thirty years! We get it - you had a crush on this "Calvin" but you've had this irrational grudge against Lorraine for more than 30 years! It is completely insane you think that Lorraine's son - a boy born more than 15 years after this "Calvin" guy left town and was never seen again - isn't George McFly's son. And it is even more insane you Lorraine "cheated" on George with some guy who hasn't been seen in this town since 19-fucking-55! Jesus, Karen, this obsession you have with Lorraine McFly really needs to end.

And no one but you remembers what "Calvin" looked like because he was here in town for like 3 weeks when we were in high school thirty years ago, Karen.
