"The Americans" joke

Two Mississippians are walking down different ends of a street toward each other, and one is carrying a sack. When they meet, one says, "Hey Tommy Ray, what'cha got in th' bag?"
"Jus' some chickens."
"If I guesses how many they are, can I have one?"
"Shoot, ya guesses right and I'll give you both of them."
"OK. Ummmmm. . . five?"
