The funniest thing is that although she wrote the alphabetization program, she still had to type in all the words by hand. Printing was very slow in that day, so she stayed up all night waiting for it to crunch out copies. The next day, she showed it to her professor, who pointed out that the word "fourty" should be "forty." So she pulled another all-nighter to get out the corrected version, seeing as the deadline was for selling it on April Fool's Day.
