This assignment is due before 9 AM, Friday, December 1^st, 2000.

• Puzzle solutions are due by 9:00 AM on Friday of each week.
• Puzzles are worth 5 points of extra credit each.
• Answers must be accompanied by valid reasoning. Just like the tests, the answer alone isn't enough!
• Each week, the first student to submit a correct answer will recieve the stylish 251 T-shirt.
• Previous winners get a "virtual t-shirt." No shirt, but a chance to win a prize with actual value at the end of the semester (often a book, or maybe software).
• Please enter your solution in the text area at the bottom of this page. DON'T FORGET TO GIVE YOUR NAME!

This is a two week puzzle worth ten points, partial credit will be awarded. Happy Thanksgiving!
