The difference between Las Vegas and Atlantic City is the difference between getting conned by a beautiful call girl and getting mugged by a crack head.

Carey uses a deliberately crude, comic analogy to contrast two gambling destinations as different kinds of risk. Las Vegas, in his framing, is seductive and polished—an environment that entices you into overspending or being “conned” through glamour, service, and spectacle. Atlantic City is depicted as harsher and more overtly threatening—less about allure and more about blunt danger. The joke hinges on the idea that both places can take your money, but one does it with charm while the other does it with intimidation. Beyond city rivalry, the line satirizes how consumers tolerate exploitation when it is packaged attractively.
