"I can usually judge a fellow by what he laughs at"

This quote by Wilson Mizner recommends that a person's sense of humor can be an excellent indicator of their character. By observing what someone finds amusing, we can get insight into their values, beliefs, and interests. For instance, someone who makes fun of jokes that are terrible or demeaning may have a different moral compass than somebody who makes fun of jokes that are smart or amusing. In addition, somebody who makes fun of jokes that are self-deprecating might have a different outlook on life than somebody who makes fun of jokes that are boastful. Eventually, this quote suggests that laughter can be a window into someone's character and can be used to judge their character.
