“Bubba, what you got in thet bag?”, he asked.
Bubba said, “I gots me some chickens in this here bag!”
Billy Bob said, “Bubba, if I guess how many chickens you got in thet there bag, can I have half of them?”
Bubba says, “Billy Bob, if you guess how many chickens I got in this here bag, you can have them both!”
Billy Bob thinks for a minute and says, “Seven!”
