Dilbert shows Dogbert a mud flap and says, "I bought some mud flaps with the silhouette of a naked woman." Dilbert continues, "With these on my car, women will think I'm a sexist Neanderthal, and men will be embarrassed to share my gender." Dilbert continues, "But now I'm having second thoughts." Dogbert says, "That implies you had first thoughts."
Ratbert says to Dogbert, "I think I'm evolving into a flying rat." Ratbert continues, "I noticed that my arms are flatter than my parents' arms. In a million years this natural advantage will become wings!" Dogbert says as Ratbert walks away, "There goes the happiest rat I know." Ratbert flaps his arms and thinks, "Too soon."
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?"
