A duck walks into a bar and says "Got any bread?" The bartender says "No bread here." And then the duck says "Got any bread?" And the bartender says "Didn't I just f***ing say that there was no bread here?" And the duck says "Got any bread?!" And the bartender says "You stupid duck! Or should I say d***? There's no bread here. Don't make me say that again, or I'll pin you to the wall with a nail." So the duck says "Got any nails?" And then the bartender looks surprised, and says "Of course I've got f***ing nails. Can't you see them?" And the duck says "Got any bread?" And the bartender throws the duck out of the bar.
