Duck goes into a bar and asks the bartender, 'Got any Grapes?", bartender replies, 'This is a bar, not a grocery store, so no we ain't got any f'n grapes" This repeats every day for about a week, when the bartender finally tells the duck that if he ever asks for grapes again he will nail the duck's feet to the f'n floor.
The next day the duck comes in and asks the bartender "Got any Nails?" Bartender replies "no, we ain't got any f'n nails" so the duck asks, "Well then, got any grapes?"....
