“A guy walks into a bar…” is a typical form of what has been called the “bar joke.” A soccer version is:
 
“A soccer ball walks into a bar, and the bartender kicks him out.”
 
The joke has been cited in print since at least 2008. “A baseball walks into a bar, and the bartender throws him out” is a similar joke.
