A pipe dream is a fantastic hope or plan that is generally regarded as being nearly impossible to achieve. The term derives from the opium pipe, and dates to the late nineteenth century when opium smoking was common in the United States. More specifically, the term derives from the euphoric optimism that is one of the effects of smoking high quality opium. Depending on how much opium is smoked, intoxication may last from eight to twelve hours. During this time smokers go through a period of euphoria followed by a more relaxed state of contentment and well being. Beginning in the late nineteenth and early twentieth centuries, popular literature and music began using the term "pipe dream" to describe any idea or plan whose probable outcome would never reach initial expectations.

B: Well, to be honest, I think it's a pipe dream.
A: Why do you say that?
B: Well, first of all, he's not a good basketball player. He's short. And he's almost 30 years old.
A: Yeah, I guess it is a bit of a pipe dream.
