What’s the difference between Dubai and Abu Dhabi?

This joke plays on cultural stereotypes and the names of two cities, Dubai and Abu Dhabi, by referencing “The Flintstones,” a popular American animated television series. The joke starts as if it will highlight a significant cultural or social difference between Dubai and Abu Dhabi, which creates an expectation of a serious or insightful observation. Instead, it takes a humorous turn by using a play on words.
The punchline, “people in Abu Dhabi doooooo,” mimics the elongated way the character Fred Flintstone shouts “yabba dabba doo” in the show. The humor arises from the unexpected and light-hearted connection between the names of the cities and a catchphrase from a cartoon, contrasting with the serious comparison anticipated by the listener.
