“A guy named Bart walks into a bar…” (bar joke)

“A guy walks into a bar…” is a typical form of what has been called the “bar joke.”  A Bart/bartender version is:
 
“A guy named Bart walks into a bar, he immediately gets shot and dies. Who killed him? The Bartender.”
 
The joke was posted on Reddit—Jokes on March 19, 2020, but there had been earlier versions.
 
“So, a guy named Bart walks into a bar, and the Bart ender hands him a large glass of poison” was posted Twitter by Phil NO MEANS TESTING on June 22, 2012. “*Bart walks into a bar* *Bart is immediately killed* I’m not a bartender, I’m a Bart Ender” was posted on Twitter by Motley-19 on January 22, 2019.
   
“I want to be a bartender.  Men named Bart… look out” is a similar joke.
