Here's an abridged version of a duck joke:
A duck walks into a bar. He hops up onto the stool, and waddles across the bar. He tugs on the bartender's sleeve, and asks, "Hiya. Got any corn?"
The bartender looks around, finally looks down, and says "What the hell? A duck? No, dammit, I don't have any corn. Now get outta here!"
The duck flutters down to the floor and waddles out the door.
The next day, the duck comes back in, hops up onto the stool, and this time, just peers over the bar, and says out loud, "Hey bartender, got any corn?" The bartender says, "Not you again! Now listen to me, duck. I don't serve ducks, I don't have any corn, and if you come back in here again, I'm going to nail your little webbed feet to the door over the mens room!" The duck squaks and leaves the bar, mumbling to himself, "What the heck is wrong with that guy?"
A week later, the duck goes into the same bar. He hops up on a stool and says, "Hey bartender, you got any nails?" The bartender says, :yeah.. wait, no. Why yhe hell would I have nails for? And what the hell are you doing back in here?!" The duck says, "Good. You got any corn?"
