The Three Brothers and Their Dad

A plane was crashing, and there were three brothers and an aged dad. But there was only 3 parachutes.The first brother said, " I'm the oldest, and the most important. I should go first. So he took a parachute and jumped off. The dad said, " I  am about to die anyway, so you two take the parachutes and leave me here." The second brother said, " No, dad we two can share one and you take the last one." "No need to, brother, for our oldest brother took my backpack!" said the youngest brother.
