Carol: My teenager wants to pierce his ear. Should I let him? Dilbert: Sure. It's only a tiny hole and it heals. Carol: Good point. Narrator: Next day. Carol: Now he wants a small tattoo. Dilbert: Well, if it doesn't show... Narrator: Next week. Carol: Now he wants to grow a human ear on his back, the way scientists did with that rat. Dilbert: As long as he can cover it with a shirt when he gets a job, I see no problem. You have to let him live his own life. Narrator: One week later. Carol: He joined ISIS. Dilbert: I forgot to mention that I'm no good at giving advice.
