Recently, a University of Michigan professor took his son to the ballpark to watch the Tigers play. Before taking their seats, they hit the concession stand for drinks. The dad ordered a beer for himself and a Mike's Lemonade for his son.
Luckily, small kids take a long time to drink anything, and the boy nursed his lemonade for almost the entire game. Then all hell broke loose when a security guard noticed that the seven year old boy was drinking Mike's Hard Lemonade, a drink that contains 5% alcohol by volume.

The dad claimed he had never heard of Mike's Hard Lemonade, which has been around since 1999. This was a college professor, one that drank alcohol himself. How is it possible that an educated man, especially one that drinks adult beverages, could have such a gapping hole in his cultural knowledge?
How high is your cultural IQ? What have you discovered that you do not know that should be "common knowledge" for your culture? What kind of attempts do you make to stay "culturally in the know" or do you care?
