So a duck walks into a bar and asks the bartender. "Got any bread?"
The bartender tells him, "No."
And the duck asks again, "Got any bread?"
'I already told you, no."
Then the duck asks a third time, "Got any bread?""
This goes on a half dozen more times and finally the bartender loses his cool and yells, "Look, if you ask me if I have any bread, I'm oging to take your @#$%^& bill and nail it to the bar!"
The duck thinks for a minute, then asks, "Got any nails?"
The bartender explodes. "No!"
"Got any bread?"
