Pain

A six year old comes crying to his Mother because his little sister pulled his hair. "Don't be angry," the Mother says, "Your little sister doesn't realize that pulling hair hurts." A short while later, there's more crying, and the Mother goes to investigate. This time the sister is bawling and her brother says... "Now she knows."

Talking Frog

My 75 year old Dad was taking his daily walk through the park when he heard a tiny voice calling to him.
"Hey, mister! Pssst, mister!"
Dad looked all around, and spotted a little frog sitting in the grass looking up at him.
"Hey mister," said the frog. "A wicked witch cast a spell on me, and turned me into an ugly frog. If you'll just kiss me I'll turn back into a beautiful princess and be forever grateful."
Dad reached down, picked up the frog, put it in his pocket, and proceeded to walk on.
The frog called out to him again, "Hey! Didn't you hear me? I said if you'll kiss me, I'll turn into a beautiful princess and be forever grateful."
Dad replied, "I heard you, but at my age, I'd rather just have a talking frog!"

Put Something In It

Little Susie, a six-year-old, complained, "Mother, I've got a stomach ache." "That's because your stomach is empty," the mother replied. "You would feel better if you had something in it." That afternoon, her father came complaining that he had a severe headache all day. Susie perked up, "That's because it's empty," she said. "You'd feel better if you had something in it."
