An older man, Dilbert and Wally sit at the lunch table. The man says, "When I started programming, we didn't have any of these sissy 'icons' and 'windows.'" The man continues, "All we had were zeros and ones - and sometimes we didn't even have ones." The man continues, "I wrote an entire database program using only zeros." Dilbert asks, "You had zeros? We had to use the letter 'O.'"
