A blonde was walking down the street, carrying a brown paper bag. She ran into one of her friends.
Her friend asked, "Hey! What do you have in the bag?"
She tells her friend that she has some fish in the bag.
The friend says, "Fish! Well, I'll make you a bet. If I can guess how many fish you have in the bag, you'll have to give me one."
The blonde says, "I'll tell you what. If you tell me how many fish I have in this bag, I'll give you both of them."
