“A guy walks into a bar...” is a typical form of what has been called the “bar joke.” A popular science joke is:

“A room-temperature superconductor walks into a bar. The bartender says, ‘We don’t serve any superconductors around here.’ The room-temperature superconductor walks out without putting up any resistance.”

Brian Malow, self-proclaimed as “Earth’s Premier Science Comedian,” popularized the joke in videos from December 2008 and November 2009.

“Yttrium barium copper oxide (YBCO) walks into a bar...” is another version of the joke.
