What's the zeroth number in the Fibonacci sequence? What happens when this function is called for fib(0)? Otherwise, good solution.

Crystal and Jeremy keep modeling all their code after a Fibonacci sequence that starts with 1 1 2 3 5 ...which as a math teacher is a little odd , but I guess I could have added in some code to deal with users putting in bad data of any kind.

Yes, it's not a huge deal, and your implementation passes all the tests. Just something to think about!
