TRUE Things You Learned From Fictional Movies and TV Shows

Contrary to the current joke thread: http://boards.straightdope.com/sdmb/showthread.php?t=703288, what true things did you learn from movies or tv? For this thread, also include things that you didn’t know to be true at the time of viewing, but learned later.

I have a few that I will add later, as I just discovered that I’m late for lunch.

“Porch Monkey” is a real racial slur. Thank you, Clerks 2! (I don’t know if there is such a thing as a “donkey show” nor do I wish to know.)
