Tricky dick and deepthroat
I was in my US History class when my teacher mentioned two people by the names of Tricky Dick and Deepthroat. Come to find out That Tricky Dick was Richard Nixon (referencing Watergate). And later we found out that Deepthroat was the man who busted Richard Nixon. Is it normal not to laugh at the joke when everyone else in the class was laughing? Although it wasn't a joke.
