Observational comedy

Observational comedy is a form of humor based on the commonplace aspects of everyday life. It is one of the main types of humor in stand-up comedy. In an observational comedy act, the comedian makes an observation about something which is common enough to be familiar to their audience, but not commonly discussed. Such observations are typically presented with the phrase "Have you ever noticed...?" or "Did you ever notice...?" which has become a comedy cliché.
