I liked this one:

Two Oklahomans are walking toward each other on a country road. When they meet, the first one asks, "Hey Tommy Ray, what'cha got in th' bag?"
"Jes' some chickens", answers Tommy Ray.
"If'n I kin guess how many they are, can I have one?"
"Shoot, if'n ya kin guess I'll give 'em both to yeh."
"OK. Ummmmm . . . five?"

Drac "I don't get it... oh wait, now I... ummmmm nope, still don't =-)" imaS
