Young Guys
A college student challenged a senior citizen, saying, "It is impossible for your generation to understand my generation. You grew up in a different world. Today we have television, jet planes, space travel, nuclear energy, computers..."
Taking advantage of a pause in the student's litany, the geezer said, "You are right. We didn't have those things when we were young; so we invented them! What are you doing for the next generation?"
