Jake the farmer has an incredibly nagging wife. One day he's out in the field, she brings his lunch to him, and then sits there and berates him while he's eating. Suddenly, the mule kicks up his back legs, smacking her in the head, and it kills her instantly.
At the wake, the minister notices that when a woman offers her sympathy, Jake nods his head up and down, but when a man comes up and speaks to him, he shakes his head from side to side. The minister says to Jake, "Why was it that you nod your head up and down to all the women and shake your head from side to side to all the men?"
Jake says, "The women all say how nice she looks, and how pretty her dress is. The men all say, Is that mule for sale?'"
Here we are in Sex Education Class. The teacher says, "All right, class, I want you to go home and come back tomorrow with as many positions as you can think of for having sex."
The next day she calls on Little Johnny in the back, "Well, John, how many positions did you come up with?" Little Johnny says, "Seventy-three."
The teacher says, "Oh, my goodness...uh...very good, John, very good..."
Next she calls on Becky in the front and says, "All right, Becky, how about you?" Becky says, "Gee, teacher, I only came up with one...where the guy just lays on top of the girl."
From the back Little Johnny yells out, "Seventy-four."
