a monkey goes into a florists and asks for some bananas, "sorry sir we are a florist we dont sell bananas"
The next day the monkey goes in and again asks for bananas " I told you yesterday, we don't don bananas, we are a florists"
The next day in walks monkey and again asks for bananas "look you stupid simeon, the next time you ask me for bananas I'm gonna nail your hands to the counter, WE DON'T SELL BANANAS!"
Next day in walks monkey and cheerfully asks if they sell nails, confused the florist says no, "you got any bananas then?"

I told a pal this joke over MSN and it really provoked a nice philosophical discussion. Dont say that Blonde isnt thought provoking. You can tell its 5 and knocking off time for most people. Arguments and discussions get more sophisticated as the day goes on It starts with me telling the punchline of the joke.
Caution, some poor language at times!!!

maire says:
heard it, except it was a duck, grapes and a bar
NY = says:
why woiuld a duck want grapes?
maire says:
your telling a joke with a TALKING duck/monkey and you wonder why it wants grapes?
NY = says:
yeah
maire says:
how about wondering how the fuck the duck is talking insted of its fucking diet. maybe its a fucking helth freak
NY = says:
but why grapes? why not pears? i think the talking part is not the essential part of the joke its more the entree to the main event, which, in your case, is the grapes
maire says:
i'd say the nails are the most important thing in the joke. why the fuck is the monkey looking for bananas in a florist?
NY = says:
thats the point of the joke you f**king idiot
NY = says:
if he went into a fruit shop they would have the bananas
maire says:
so he's knowingly going in for something that they dont have. therefor it the object that he wants is of no concequnce. he knows he cant get it. therefor it doesnt matter what he wants. grapes, bananas peanuts it doesn't matter, he knows he's not going to get it so it doesn't matter if he wants it or not. your the f**king idiot
NY = says:
he wants the bananas but if he went into a fruit shop it wouldnt make for a great joke
maire says:
he's not going in for something he wants.he's going in for something they dont have. thats his rouse. if he really wanted the bananas then he would, as you have said, gone to the fruit shop
NY = says:
maybe their is no fruit shop on his way from his house to his place of work?
maire says:
then why go in three times. if he's intelligent enough to speak then he's intelligent to know that a flower shop doesn't sell fruit. at least after the first time he asks. you've lost, give it up
NY = says:
look this debate is over. The talking part is not important. the object he wants generates interest in the joke. monkeys want bananas. Why would a duck want a grape?? thats my point
maire says:
your point is mute. you have not grasped the joke, and on a side note many would argue that the abstractness of a duck asking for grapes adds to the humour of the joke
