Thanks for the suggestions. I'll try them out on my test box when I

What is the meaning of Life?

To search for truth and beauty.
To ask questions.
To find the answer to this question
To rigorously mathematically prove by epislon-delta treatment that this 
question has no answer. Proof? For all oranges greater than zero, there exists 
a banana such that for all fruits tastier than the banana, an orange sweeter 
than a banana implies the orange is yellow. So by the Jedi-Schwartz Inequality,
all oranges are not orange. This leads to an obvious contradiction.

It's too bad life is a departmental requirement, otherwise I'd P/D/F it.
