Deja-Vu The Doctor set his paper down and stared at Benny across the cafe table. "That's strange. I'm suddenly having this incredible sensation of deja-vu." "Really?" There was a pause, and then Benny leaned across the table at him and chanted, "Booga, booga, booga, booga, booga." He jerked back in astonishment. "What are you doing?!" "Have you ever heard me say those words before?" "Of course not!" "Well, there you go! That should take care of your feelings of deja-vu." He snorted, then turned back to his paper. "Very good. But you do realize, you can only use that once."
