“A guy walks into a bar…” is a typical form of what has been called the “bar joke.” A quality assurance (QA) engineer version is:
   
“A QA engineer walks into a bar. Orders a beer. Orders 0 beers. Orders 999999999 beers. Orders a lizard. Orders -1 beers. Orders a sfdeljknesv.”
 
The joke about what a QA engineer does was posted on Twitter by Bill Sempf‏ on September 23, 2014. The joke has been printed on many images.
 
“A QA testing engineer walks into a bar. Runs into a bar. Crawls into a bar. Dances into a bar. Tiptoes into a bar. Rams into a bar. Jumps into a bar” and “A software tester walks into a bar and then runs into the bar… strolls into the bar… gallops into the bar… saunters into the bar…” are similar jokes.
