lol!! Nice joke :P
Here, I rewrote it:
there were 3 ducks in a pond blowing bubbles, minding their own business, when a cop comes by and says "this is a provincial park, and your kind is not supposed to be in here, so get out!"
So the ducks come out of the water and the cop asks them their names. The first duck says his name is Daffy, the second says his name is Donald. The cop points at the last duck, who is trying to hide, and says "You haven't told me your name yet!" The duck says "my name is bubbles".

WHere did "daisy" come from, btw?
