A Bad, Bad Joke

Little Johnny's father sat down next to him on the couch one day and said, "Okay, Johnny, once there was this big, black rooster, and it was sitting on a fence post. How many wings does the rooster have?"
Johnny replied, "It has two."
Little Johnny's father then asked, "How many eyes does the rooster have?"
Johnny replied, "It has two."
Little Johnny's father then asked, "Well then, how many legs do you think the rooster had?"
Johnny replied, "It has two, Daddy."
So then, Little Johnny's daddy said, "Well then, a little white cat walks up to where the big black rooster is standing on the fence post and opens its mouth to hiss at the rooster.
How many teeth does the cat have?"
Little Johnny scratched his head and replied, "I don't know Daddy, how many teeth does the cat have?"

Little Johnny's daddy grabbed him by the arm and exclaimed, "Alright boy, how come you know so much about big black cock and so little about white pussy?"
