+# Bob
+
+Bob is a lackadaisical teenager. In conversation, his responses are very limited.
+
+Bob answers 'Sure.' if you ask him a question.
+
+He answers 'Woah, chill out!' if you yell at him.
+
+He says 'Fine. Be that way!' if you address him without actually saying anything.
+
+He answers 'Whatever.' to anything else.
+
+## Instructions
+
+Run the test file, and fix each of the errors in turn. When you get the first test to pass, go to the first pending or skipped test, and make that pass as well. When all of the tests are passing, feel free to submit.
+
+Remember that passing code is just the first step. The goal is to work towards a solution that is as readable and expressive as you can make it.
+
+Have fun!

+# Leap
+
+Write a program that will take a year and report if it is a leap year.
+
+The tricky thing here is that a leap year occurs:
+
+```plain
+on every year that is evenly divisible by 4
+  except every year that is evenly divisible by 100
+    unless the year is also evenly divisible by 400
+```
+
+For example, 1997 is not a leap year, but 1996 is.
+1900 is not a leap year, but 2000 is.
+
+If your language provides a method in the standard library that does this
+look-up, pretend it doesn't exist and implement it yourself.
+
+## Notes
+
+For a delightful, four minute explanation of the whole leap year phenomenon, go watch [this youtube video](http://www.youtube.com/watch?v=xX96xng7sAE).
