Two brothers were playing, when the little brother asked whether he could fly like Superman. “Why, sure you can,” encouraged the older brother, “just flap your arms really really hard.”
So, his little brother climbed up onto the windowsill, started flapping like mad, then jumped, smashing onto the ground just a few feet below. Hearing her child’s cries, their mother came flying into the room, and, seeing her son out on the lawn, asked, “What the heck is going on here?” The older brother looked at his mother innocently, and said, “I was just teaching him not to believe everything that someone tells him, Mom.”
