“A guy walks into a bar…” is a typical form of what has been called the “bar joke.” A joke involving Jesus (who can turn water into wine) is:
 
“Jesus walks into a bar and says, ‘I’ll just have a glass of water.’”
   
The joke has been cited in print since at least 1996.
 
“Jesus walks into a bar. The barman looks up and asks, ‘We don’t serve wine here.’ Jesus looks at him quizzically and goes to look for a Spanish translator because he had just immigrated from Mexico and English was not his first language” is a “Jesus walks into a bar” anti-joke.
   
       
Wikipedia: Marriage at Cana
The transformation of water into wine at the Marriage at Cana or Wedding at Cana is the first miracle attributed to Jesus in the Gospel of John. In the Gospel account, Jesus, his mother and his disciples are invited to a wedding, and when the wine runs out, Jesus delivers a sign of his glory by turning water into wine.
 
The location of Cana has been subject to debate among biblical scholars and archeologists; several villages in Galilee are possible candidates.
