A blonde is walking along a road with a sack of chickens in her bag. After a while, she bumps into another blonde. "Watcha got in there?" the second blonde asks. "Chickens," the first blonde replies. "If I can guess how many chickens you got in there, will you give me one?" the second blonde asks hopefully. "Well, if you can guess how many chickens are in here, I'll give you both of them," the first blonde says. "Ummm... five?" replies the second blonde.
