I've said it before, I'll say it again, there is nothing quite like a game based on stuff out of our childhood. And what is more childlike the anything from Dr. Suess? For this fine game you will need people, beer, and either the book or video of "How the Grinch Stole Christmas." If you choose the book, then choose somebody with good storytelling skills to be the narrator.
Only one rule for this game: anytime the word "who" is said, take a drink. "All the Who's down in Whoville" would be two drinks.
