Dilbert sits in his chair and Dogbert sits on Dilbert's legs. Dogbert says, "You shouldn't care so much about what other people think of your work." Dogbert continues, "I mean, everybody scoffed at the Wright Brothers. Galileo was jailed. Columbus was ridiculed." Dogbert continues, "'Course, none of those guys had a head shaped like a torpedo."
Dilbert sits at his desk and Ratbert sits on the desk holding his arms out. Dilbert says, "Evolution takes millions of years, Ratbert. You'll be long gone before rats develop flying skills." Ratbert replies, "That's what they said to the Wright brothers." Dilbert says, "But THEY built an airplane." Ratbert flaps his arms and asks, "Don't you think they tried this first?"
