"What does it mean to pre-board? Do you get on before you get on?"

This quote by George Carlin is a humorous method of mentioning the absurdity of the phrase "pre-board". Pre-boarding is a term used in the airline industry to refer to the process of allowing particular passengers to board the aircraft prior to other passengers. This is usually done to accommodate guests with unique requirements, such as those with specials needs or those traveling with kids. Carlin's quote is poking fun at the concept of pre-boarding, as it suggests that a person would have to board the plane before they even get on it. This amusing take on the phrase highlights the absurdity of the concept, and works as a pointer that language can be used in an amusing method to make a point.
