In my on-going search or Easter Eggs in Episode 4, I sumbled upon a joke I didn't get. I looked it up as best I could, and still can't find why it's suppose to be in the game.
Here's the joke I'm talking about: When you are changing the date on the Presidential Calender, change it to Earth Day. After Sam describes what the holiday, Max says "People of Berkly, California: Keep up the good work!"
I have to admit, I laughed the first time, but didn't get it as immediately as the Apollo 13 Snowglobe joke. Even now, I don't get it. Can someone explain this to me?
