Share July 23, 1989's comic on:
Dogbert stands inside the house looking out the window. A bird flies into the window and bounces off. The bird knocks on the door. Dogbert answers the door and the bird says, "Excuse me, mammal. Would you please lower your invisible force field so I can fly through?" Dogbert replies, "That's no force field; that's a window." The bird enters the house and says, "Oh, worms! I'm always making that mistake. We birds can be pretty stupid sometimes." Dilbert says, "Hi, little bird. You look thirsty. Would you like some water?" The bird replies, "Sure." Dogbert says, "Don't put it in a glass; he might beat his brains out with it."
