Dilbert is at the Boss's desk. The Boss tells Dilbert: "Don't invite marketing to the planning meeting." Dilbert replies: "If I don't, they'll sabotage the implementation." The Boss says: "Yes, but if you DO include them in the planning..." Dilbert finishes the Boss's thought: "...they'll hose the plan?" The Boss confirms Dilbert's statement: "Exactly." The Boss continues: "And they'll still botch the implementation." Dilbert asks: "If we know it's doomed, why do we bother?" The Boss answers: "It's the same reason I had kids." Dilbert thinks to himself while walking away: "At least there is a reason."
