"My cousins gay, he went to London only to find out that Big Ben was a clock"

In this quote, comic Rodney Dangerfield is making a joke about his cousin's sexual preference. He says that his cousin is gay and went to London, presumably to explore the city's LGBTQ+ neighborhood. Nevertheless, instead of discovering what he was searching for, his cousin finds that Big Ben, a famous landmark in London, is just a clock. This joke uses the stereotype that gay people are more thinking about fashion, culture, and nightlife, instead of historical landmarks. It also highlights the idea that sometimes, what we are searching for is right in front of all of us along. Overall, this quote is a humorous commentary on stereotypes and expectations.
