Two men sank into adjacent train seats after a long day at work. One asked the other, "Did your son go back to college yet?" "Yep. Two days ago." "Hmm. Mine's a senior this year, so it's almost over. In May, he'll be an engineer. What's your son going to be when he gets out of college?" "At the rate he's going, he'll be about thirty." "No, I mean what's he taking in college?" "Every penny I have." "Doesn't he burn the midnight oil?" "He doesn't get in early enough to burn the midnight oil." "Surely sending him to college has some benefit?" "Well, it has cured his mother of bragging about him!"
