So two farmers are standing next to a cow and one farmer says: 1st guy: "Hey Larry, you know how your birthday's tomorrow?" 2nd guy: "Uh huh." 1st guy: "I made a cake." 2nd guy: "Uh huh." ......*long pause*...... Cow: "Hey Larry, you know how your birthday's tomorrow?" 2nd guy:"Uh huh." Cow: "I made a pie." 2nd guy:"Uh huh."
