Dilbert and Dogbert walk outdoors. Dilbert says, "I thought I was happy . . ." Dilbert continues, "Then I thought what if I only THINK I'm happy but I'm not. Maybe I've been hypnotized and don't even know it." Dilbert continues, "Worrying about it made me unhappy, which means I must NOT be under hypnosis, so I'm happy." Dogbert replies, "Maybe I only THINK you're talking but really I'm happy."
