Desert Island must haves.

Following a discussion, i got to thinking if you were stuck on a desert island, what 3 things would you take with you? You can take one other ARRSER who would it be and why?

For me it would be
1. Chocolate
2. A knife
3. Mirror
and the_Iron because he seems to know everything about everything, well when he is sober...
This is a fantastic thread for Rear Party, its been done here and it was a box of trump the first time round
