“A guy walks into a bar…” is a typical form of what has been called the “bar joke.” “A duck walks into a bar and asks, ‘Got any grapes?’” is one of the most popular bar jokes. The bartender says that he doesn’t have any grapes, but the duck keeps returning and asking the same question. Finally, the bartender says that he’ll nail the duck’s bill to the bar if the duck asks that question one more time. The duck returns, this time asking, “Got any nails?” When the bartender says “No,” the duck asks again, “Got any grapes?”
 
The joke has been cited in print since at least 1996. The joke was popularized in the YouTube video The Duck Song (2009), where a lemonade stand was used instead of a bar.

A duck walks into a convenient store and walks up the counter. The duck asks, “Got any grapes?” “No,” said the puzzled store clerk. The duck smiles and walks out the door. A little while later the duck returns and asks, “Got any grapes?” The clerk replies, “No! Like I already told you 15 minutes ago, I don’t have any grapes!” The duck smiles and walks out. A little while later the duck returns and again asks “Got any grapes?” The irate clerk yells, “No! We didn’t have any, we don’t have any, and were not going to have any. If you come back in here again I’ll nail your webbed feet to the floor!” The duck smiles and walks out. Later the duck returns and asks the clerk “Got any nails?” The clerk says “NO!” The duck replies, “Good! Got any grapes?”—from Dave Diehl, 6/19/1996
