A duck goes into a bar and askes the bartender,
"You got any fish?" The bartender replies, "No,
this is a bar and we don't sell fish," so the duck
leaves. The next day, the duck goes back to the
bar and asks, "You got any fish?" The bartender
says, "I told you yesterday, this is a bar and we
don't sell fish!" The following day the duck returns
and says, "You got any fish?" The bartender loses
it, grabs the duck by the neck and screams,
"I TOLD YOU TWICE, THIS IS A BAR. WE
DON'T SELL FISH. IF YOU ASK
AGAIN, I'M GONNA NAIL YOUR WEBBED
FEET TO THE FLOOR!" The next day, the duck
goes into the bar and asks, "Got any nails?"
The bartender sighs and says, "No, we don't have
any nails." The duck says, "Good. Got any fish?"
